Antibody News and Research

RSS

An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Structure function analysis of potent antibodies against Beta SARS-CoV-2 variant

A team of researchers from UK and US institutions created a large panel of mAbs derived from memory B cells of convalescent Beta subjects to better understand the antigenic landscape of Beta.
