Antigen

MyBioSource is the world leader in providing high quality and diverse range of antigens for research applications.

An antigen is typically defined as a substance that triggers an immunogenic response. The immune system sees the antigen as a foreign substance; that is, something that is non-self. The production of antibodies by B-cells, specialized cells of the immune system, is the most well-known immunogenic response triggered by antigens.

An antigen may be a recombinant or native protein, partial protein, synthetic or natural peptide, chemical, toxin, viral or bacterial component, standard or reagent for ELISA assays, as well as an environmental agent.
