Goat F(ab')2 anti-human IgA Capture antibody - IgAα chain specific Goat F(ab’)2 anti-human IgA was generated from antibodies isolated from antisera of goats hyperimmunized with human IgA paraproteins. Antibodies were purified by affinity chromatography and digested by pepsin to remove the Fc portion, to avoid non-specific binding through Fc receptors. Goat F(ab’)2 anti-human IgA allows the capture of the heavy chain of human IgA antibodies. Source: Pepsin digest of goat anti-human IgA Cross Absorption: Human IgM, IgG and IgD Purification: Gel filtration chromatography of pepsin digested antibody Specificity: Reacts with the heavy chain of human IgA as demonstrated by ELISA and flow cytometry. May also react with IgA from other species.
