Goat anti Human IgA antibody recognizes the heavy chain of human IgA as demonstrated by ELISA and Flow cytometry. IgA is the major catagory of antibody present in mucosal secretions and acts as a first line of defense against inhaled or ingested pathogens at the mucosal interface. IgA is also present in serum where it acts to eliminate pathogens via interaction with FcαR, also known as CD89. (Woof et al. 2004).
Biotinylated Goat anti Human IgA antibody (205008) has been cross-adsorbed against human IgD, IgG and IgM to ensure class specificity.
