Cusabio Organism Recombinants


The discoveries of the double-stranded structure of DNA and the development of recombinant DNA technology sparked a revolution in industrial microbiology. Traditional industrial microbiology merged with molecular biology to produce improved organism recombinant processes for the industrial production of primary and secondary metabolites, biopharmaceutical proteins, and industrial enzymes. New genetic techniques such as metabolic engineering, combinatorial biosynthesis and molecular breeding techniques and their modifications are greatly contributing to the development of improved industrial processes.

Furthermore, functional genomics, proteomics and metabolomics are being exploited for the discovery of new small molecules valuable for medicine, as well as enzymes for catalysis. Sequencing of industrial microbial genomes is ongoing, which bodes well for future process improvement and the discovery of new industrial products.

Amino acids.

Genetic engineering has impacted amino acid production through the use of the following strategies: (1) amplification of a rate-limiting enzyme pathway; (2) amplification of the first enzyme after a branch point; (3) cloning of a gene encoding an enzyme with more or less feedback regulation; (4) introduction of a gene encoding an enzyme with a functional or energetic advantage as a replacement for the normal enzyme; and (5) amplification of the first driving enzyme from central metabolism to increase carbon flux in the pathway followed by sequential removal of bottlenecks caused by the accumulation of intermediates.

Transport mutations have also become useful, that is, a mutation that reduces amino acid uptake allows for enhanced excretion and lower intracellular feedback control. This has been especially useful in the production of tryptophan and threonine. In cases where excretion is mediated by transporters, increased activity of these transporter enzymes increases amino acid production.

Other compounds.

Nucleosides. Genetic engineering of the inosine monophosphate (IMP) dehydrogenase gene in a B. subtilis strain that produces 7 gl−1 desirable guanosine and 19 gl−1 undesirable inosines changed the production to 20 gl−1 guanosine and 5 gl −1 inosine. Guanosine is used to produce guanosine monophosphate (GMP), a powerful flavouring agent.

Carotenoids. Carotenoids were overproduced by the introduction of Erwinia uredovora carotenoid gene clusters into E. coli and overexpression of E. coli deoxyglucose phosphate synthase, the key enzyme of the non-mevalonate isoprenoid biosynthetic pathway zeaxanthin at 0.6 mg g−1.

Glucosamine. Glucosamine is used for osteoarthritis and is produced by acid hydrolysis of chitin from shellfish waste. Since many patients have shellfish allergies, a microbial source is desirable. Metabolic engineering of E. coli produced a process that produced 17 gl−1 of glucosamine. In this strain, glucosamine synthase was overexpressed, glucosamine-degrading genes were inactivated, and glucosamine inhibition of glucosamine synthase was decreased. by mutational modification of the enzyme through error-prone PCR. Overexpression of a heterologous glucosamine-6-P-N acetyltransferase produced a strain that produces 110 g l -1 of N-acetylglucosamine which is readily converted to glucosamine by mild acid hydrolysis.

Solvents. Cloning it’s as (acetone) ADC operon genes (encoding acetoacetate decarboxylase), and CTF and CTF (two genes encoding coenzyme A transferase) into a plasmid containing the ADC promoter in Clostridium acetobutylicum resulted in a 95% increase % in the production. The increases were 95% in acetone production, 37% in butanol, 90% in ethanol, 50% yield of solvent from glucose, and 22-fold lower production of undesirable acids. The introduction of the acetone operon of C acetobutylicum in E. coli led to the high production of acetone by the latter.

Novel Coronavirus (SARS-CoV-2) and Influenza A/B Virus RT-qPCR Detection Kit

Expected use

The SARS-CoV-2/Influenza A&B/RSV RT-qPCR Combo Kit is CE marked, in vitro diagnostic real-time reverse transcriptase PCR (RT-PCR) assay intended to be used for the identification and quantification of COVID-19 viral RNA extracted from Nasopharyngeal swabs and/or oropharyngeal swabs. The assay is designed to be used with designated extraction systems and PCR platforms. The combined SARS-CoV-2/Influenza A&B/RSV RT-qPCR Kit (CE IVD) assay is intended for use by specifically instructed and trained qualified and trained clinical laboratory personnel in real-time PCR techniques and in vitro diagnostic procedures.

Purpose, Scope and Users

SARS-CoV-2 has initially named the 2019 novel coronavirus (2019-nCoV) and was identified by Chinese authorities after an outbreak of pneumonia in December 2019 in Wuhan, Hubei province, China. The WHO declared an international health emergency on January 31, 2020. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) recommend random testing for the asymptomatic population and testing for anyone with symptoms of samples collected from the upper airways and/or lower airways specimens for the identification of SARS-CoV-2 and other respiratory viruses, such as influenza and RSV. RT-qPCR is the gold standard method to identify active infections.

The NIPD Genetics Combined SARS-CoV-2/Influenza A&B/RSV RT-qPCR Kit is a Multiplex real-time RT-qPCR assay for the direct qualitative detection of RNA from 4 viruses: the new coronavirus (SARS-CoV-2), influenza A, influenza B and respiratory A/B syncytial virus (RSV A/B) from human respiratory specimens collected through the Nasopharyngeal and/or oropharyngeal swab method. Validation was performed on the QIAquant 96 5plex real-time PCR instrument (230 V) Real-time PCR detection system. This test can distinguish between influenza A and B subtypes, but not differentiate between RSV A and B. RNA is isolated from respiratory samples, reverse transcribed and amplified using RT-qPCR and detected with four fluorescent dye probes, allowing multiplexing and co-detection by sample reaction.

Fundamental reason

Diagnosis of the aforementioned viruses can be challenging due to the likeness of the symptoms. However, discriminatory and early diagnosis is important for the disease management and treatment, therefore, real-time PCR assay can be a sensitive method and reliable method to detect SARS-CoV-2, influenza A/B and RSV viruses. NIPD Genetics is not responsible for the outcome of a patient’s treatment if the results are being used to guide the medical treatment of health professionals.

Quality control and validity of the results

SARS-CoV-2/Influenza A&B/RSV RT-qPCR Combo Kit Contains Positive Results (PTC) and negative template controls (NTC) to be able to control the PCR amplification. Both of them controls should be included in each run for proper quality control, interpretation of results, and for the results to be considered valid.


  • Coronaviruses

are single-stranded, positive-sense, non-segmented RNA viruses. They belong to the Coronaviridae family. They are the largest known RNA viruses with genomes ranging between 27 and 31.5 kb. There are six species of coronaviruses known to causes human diseases 229E, OC43, NL63, HKU1, MERS-CoV, and SARS-CoV. SARS-CoV-2, named as a 2019 novel coronavirus (2019-nCoV) is responsible for the current pandemic that affects millions of people around the world. The virus is transmitted from human to human through respiratory droplets by direct or indirect contact.

Symptoms of SARS-CoV-2 can appear 2 to 14 days after exposure to the virus and at most common symptoms are fever, dry cough, fatigue. Less common symptoms include aches and pains, nasal congestion, sore throat, diarrhoea, loss of smell (anosmia) or loss of taste (ageusia), etc. The strongest and most consistent evidence of increased risk comes from patients with a BMI greater than 30 kg/m2, type 2 diabetes mellitus and with underlying lung and heart conditions, who are more likely to develop complications and require ICU admission and oxygen support.

  • Influenza viruses

are negative-sense viruses that belong to the Orthomyxoviridae family. The most common influenza viruses that infect humans are influenza A and B. The most common symptoms include fever, cough, sore throat, nasal congestion, and discharge that can lead to more serious complications of pneumonia. age and underlying pulmonary medical conditions (eg, COPD, IPF, asthma, smokers) increase the risk of developing complications.

  • Human respiratory syncytial viruses (RSV)

are non-segmented, negative, viruses with single-stranded linear RNA genome belonging to the Paramyxoviridae family. RSV causes respiratory infections in humans, including bronchitis, pneumonia, and chronic obstructive pulmonary infections. Common symptoms include runny nose discharge, low-grade fever, cough, sore throat, headache, and wheezing. All of the aforementioned viruses are transmitted between humans in three ways: (1) directly contact with infected people; (2) by contact with contaminated objects (such as toys, doorknobs); and (3) by inhalation of virus-laden aerosols.

General rules

1. Transport and storage conditions

Reagents are shipped and stored at -20°C until the expiration date, as indicated on the label. To minimize freeze-thaw cycles and preserve the integrity of the PTC, we recommend aliquoting and storing at -20°C. All components must be kept away from sunlight.

The Myth of IgG Food Panel Testing

IgGEs Food Panel Test Very common for patients to feel they have food allergies or food intolerances/sensitivities. These terms or labels are often used interchangeably. However, it is important to understand that allergies are very different from intolerances or sensitivities. There are excellent materials on this website to help you distinguish between the two. With a food allergy, the body mounts an immune response to the food, and this can be dangerous. With an intolerance or sensitivity, the body may simply not be processing or digesting food properly and this is not really dangerous (although it can obviously be uncomfortable).

More classic food intolerances (such as lactose intolerance) cause patients to experience bloating, fullness, stomach pain, gas, and/or diarrhoea when they eat too much food. This is because the body is not digesting food properly, leading to a buildup of air and gases in the stomach and intestines. Other patients experience headaches, fatigue, “brain fog” or stomach pain with various foods or additives/preservatives. Oftentimes, patients feel that multiple foods may be causing these symptoms and are hoping to find a single test that will tell them exactly which foods to avoid so they can simply feel better.

Unfortunately, there is no single test that can give you this answer. One test that claims to be able to diagnose food sensitivities and is commonly available in the food IgG test. This test, offered by several companies, reports IgG levels for multiple foods (typically 90 to 100 foods with a single panel test) and claims that eliminating foods with high IgG levels can lead to improvement in multiple symptoms. Some websites even report that diets using this test can help with symptoms of irritable bowel syndrome, autism, cystic fibrosis, rheumatoid arthritis, and epilepsy.

It is important to understand that this test has never been scientifically proven to do what it claims to do. The scientific studies provided to support the use of this test are often out of date, in unaccredited journals, and many have not even used the IgG test in question. The presence of IgG is probably a normal response of the immune system to food exposure. In fact, higher levels of IgG4 to foods may simply be associated with tolerance to those foods.


COVID-19 Ag Rapid Test

The COVID-19 Rapid Antigen Test, a lateral flow chromatographic immunoassay, looks for protein fragments of the virus and thus its direct physical presence in the body. It is performed using a swab from the oral cavity or from the nasopharynx. This is extracted into a buffer solution and then pipetted into the test cassette. A qualitative result is ready in less than 20 minutes.

The diagnostic sensitivity is 97.56% (ct value: 20 – 30) and the diagnostic specificity is >99.9%. That means positive antigen test results are highly accurate. However, as there is always a residual risk of a false negative result if, in doubt, a PCR test should be performed to confirm negative results. The choice between antibody, antigen, and PCR testing is not a one or other decision. Rather, the best tactic is a combined application.

Test properties:

  • Optimized testing process
  • High specificity (>99.9%)
  • Highly sensitive with high viral loads: 97.56% (ct value: 20 – 30)
  • Easy to use
  • Fast and reliable test results in just 15 minutes
  • Testing can be performed using nasal, nasopharyngeal, and oropharyngeal specimens.
  • It can be stored at room temperature.
  • All test components, including sterile swabs, are included.
  • No cross-reactivity with seasonal coronaviruses (such as hCoV-229E, -HKU1, -NL63, and -OC43) or influenza viruses (such as influenza A/B)

Importance of the antigen test

While the COVID-19 IgG/IgM Rapid Test detects the virus indirectly, the COVID-19 Rapid Antigen Test detects it directly by checking for the presence of specific proteins of the SARS-CoV-2 virus. Therefore, antigen detection closes a diagnostic gap. The nucleocapsid (N) protein is ideal for virus detection because it is highly abundant in the virus and specific enough for SARS-CoV-2. It is one of the 4 most important structural proteins of the virus and is involved in the replication, transcription and packaging of the viral genome.

The COVID-19 Rapid Antigen Test is a lateral flow chromatographic immunoassay for the qualitative detection of SARS-CoV-2 viral nucleoprotein antigens in human nasal- and oropharyngeal specimens. The test is intended to be used as an aid in the diagnosis of SARS-CoV-2 infections. It should be noted that the concentration of viral nucleoprotein antigens may vary during the course of the disease and may fall below the detection limit of the test. The possible infectiousness of test subjects cannot be excluded based on negative test results.
