COVID-19 antigen tests diagnose active infection by detecting SARS-CoV-2 viral proteins in samples, as opposed to PCR tests which detect viral RNA and require lab processing, but can miss infections with low virus levels. The test – which can also be self-collected – showed a sensitivity of 93.8%

It is important in the process of protein synthesis because mRNA is responsible for transferring genetic information from DNA to ribosomes, which then decodes the genetic information into a protein. In the last few years, researchers have become interested in using in vitro transcribed (IVT) mRNA as a drug delivery agent.
With the Omicron variant of SARS-CoV-2 continuing to run rampant, Italian in vitro diagnostics (IVD) company A.Menarini Diagnostics has unveiled a new real-time (RT)-PCR-based test that can detect several variants of the coronavirus including Omicron and Delta. We are extremely proud to have made this unique solution available so quickly.
Both the areas of drug development and clinical trials are increasingly using in vitro assays to help determine the efficacy of an investigational therapeutic. Flow cytometric receptor occupancy assays are being increasingly used in preclinical and clinical studies. What is Flow Cytometry?
Molecular diagnostic tests refer to tests intended to detect specific sequences in human genomic samples, such as DNA or RNA, in order to diagnose a particular disease. It is worth mentioning that molecular diagnostics is a subset of the broader in vitro diagnostics market.
However, DelveInsight’s Angelman syndrome market analysis report estimates that several approaches focused primarily on the Gene Therapies, Topoisomerase Inhibitors, Cannabidiol, Protein Phosphatase 2A inhibitor, among others are under development to find a cure for the Angelman syndrome. GeneTx and Ultragenyx are co-developing the therapy.
Antigen test reliably and quickly triages people suspected of SARS-CoV-2, with results ready in 15 minutes, allowing informed treatment decisions. Antigen test accurately screens individuals with known exposure to infected SARS-CoV-2 patients, providing fast answers regarding their infection status. Food and Drug Administration (FDA).
RNA therapeutics are a novel class of biopharmaceuticals that harness the power of RNA molecules for the treatment and prevention of a wide range of disorders, including oncological, and genetic disorders as well as infectious diseases. Non-coding RNAs include antisense oligonucleotides (ASOs) and RNA aptamers.
According to the US biopharma company, genetic analyses of publicly available sequences for the new variants of SARS-CoV-2 suggest the mutations in the viral spike protein that have made them more transmissible shouldn’t affect the way Veklury (remdesivir) works. The UK strain – known as B.1.1.7
Studies have identified the presence of two types of HIV-infected CD4+ T cells: ‘Transcriptionally inactive’ cells that do not typically produce viral RNA or viral proteins. Transcriptionally active’ cells in which HIV RNA is actively transcribed to make copies of the virus (despite long-term ART).
Liquid biopsy tests in oncology involve isolating entities such as circulating tumor cells (CTC), circulating tumor DNA (ctDNA) and tumor-derived exosomes. These tumor-derived entities are used to derive genomic and proteomic data. The same webinar held a Q&A session with Dr. Bahassi and two other experts from Medpace, Dr. Lyon L.
With the rapid development of biotechnology and molecular medicine, the introduction of mRNA as a vaccine or therapeutic agent enables the production of almost any desired functional protein/peptide within the human body.
“The SARS-CoV-2 vaccines target the spike protein, but this protein is under strong selection pressure and, as we have seen with Omicron, can undergo significant mutations,” said Joyce Jose, assistant professor of biochemistry and molecular biology, Penn State. ” The findings published today (Feb.
Overview of Cell Free Systems Cell-free systems are in-vitro platforms which allow occurrence of biochemical reactions in the absence of living cells. Additionally, these types of cell free systems do not contain proteases and nucleases as crude cell lysates, which further helps in improving the production of many proteins.
Messenger RNA vaccines contain nucleic acids that code for a specific protein, or target antigen, related to a virus or disease. When an mRNA vaccine is administered, a patient’s body produces that protein to prompt a desired immune response. Before COVID-19, Merck held the record for the fastest modern vaccine ever developed.
As it stands, mRNA vaccines and therapeutics can only provide benefits if they can reach the living cells and be processed into protein. The intracellular barriers include endosomal escape, RNA sensors, and endonucleases. The intracellular barriers include endosomal escape, RNA sensors, and endonucleases.
Nirmatrelvir is designed to inhibit viral replication at a stage known as proteolysis, which occurs before viral RNA replication. Current variants of concern can be resistant to treatments that work by binding to the spike protein found on the surface of the SARS-CoV-2 virus.

From leveraging artificial intelligence (AI) to streamline diagnostics and treatments to exploring the untapped potential of RNA-based therapeutics, biotechnology is shaping the future of healthcare and beyond. As of January 31, 2024, approximately 131 unique RNA-based therapies are in clinical development across various therapeutic areas.
The company’s candidate vaccine, mRNA-1273, is a synthetic messenger RNA that encodes the stabilized SARS-CoV-2 spike protein. The University of Oxford/AstraZeneca partnership, in turn, is testing a viral-vectored coronavirus vaccine that again expresses the spike protein of SARS-CoV-2 virus. Moderna’s COVID-19 Vaccine.
