Blocking Antibody

Blocking antibody is a specific type of antibody This type of antibody does not produce any visible reaction with the antigen when combines with it but blocks anything else from reacting with its antigen The function of blocking antibody is useful in clinical uses as a blocking antibody can prevent a harmful substance from binding to the cell For instance in treating allergic disorders

First Report of Human Monoclonal Antibody That Blocks

Monoclonal antibody potently inhibits SARS-CoV-2 SARS-CoV-2 and SARS-CoV both belong to the Sarbecovirus subgenus of the Coronaviridae family The trimeric spike (S) glycoproteins present on the viral surface enable entry of the virus into host cells by binding to a receptor protein known as the human angiotensin converting enzyme (ACE2)
