New anti-evolocumab antibodies could aid drug development

Drug Discovery World

Bio-Rad Laboratories has introduced a range of type 1 antibodies that inhibit the binding of evolocumab (Repatha) to its target, human proprotein convertase subtilisin/kexin type 9 (PCSK9), a protein that has been shown to play a key role in the regulation of cholesterol levels. .

New method identifies antibody-like proteins with diagnostic and therapeutic potential for SARS-CoV-2

Scienmag

Antibody-like proteins that capture and neutralize SARS-CoV-2 Scientists have used a new high-speed, in vitro selection method to isolate 9 antibody-like proteins (ALPs) that bind to the SARS-CoV-2 virus – 4 of which also exhibited neutralizing activity – within 4 days, according to a new study.

Researchers Discover Genetic Errors and Rogue Antibodies in Cases of Severe COVID-19 Infection

XTalks

The research shows that the activity of the immune messenger type 1 interferon (IFN) protein is diminished, either by genetic mutations or an autoimmune attack by neutralizing antibodies against it, in a subset of COVID-19 patients.

Turning science into business: An optimised alternative to antibodies

Drug Discovery World

DS: What motivated you and Dr David Bunka, CTO, to create Aptamer and did you imagine you would one day be operating on such a global scale?    I quickly recognised the commercial value of aptamers as being able to address the gap in the market where antibodies fail to perform, and together we established the business to begin aptamer development.

A protein-based COVID-19 vaccine that mimics the shape of the virus

The Pharma Data

Now, researchers reporting in ACS Central Science have immunized mice with nanoparticles that mimic SARS-CoV-2 by displaying multiple copies of the receptor binding domain (RBD) antigen, showing that the vaccine triggers robust antibody and T cell responses. Although the first vaccines to receive Emergency Use Authorization by the U.S.

Roche launches new quantitative antibody test to measure SARS-CoV-2 antibodies, to support the evaluation of vaccines

The Pharma Data

The new Elecsys Anti-SARS-CoV-2 S test can quantitatively measure the level of antibodies against SARS-CoV-2 in patients who have been exposed to the virus. The test targets antibodies against the spike protein. The majority of current candidate vaccines aim to induce an antibody response against the spike protein. “As
