The Mouse Anti-HAsAg Recombinant Antibody is a monoclonal antibody that specifically recognizes and binds to Hepatitis A virus antigen (HAsAg). This recombinant antibody plays a crucial role in diagnosing and researching Hepatitis A virus (HAV) infections and studying the immune response to HAV. It is also useful for developing serological assays and exploring the molecular biology of HAV.
