Goat F(ab)'2 anti-Human IgA - FITC Goat F(ab')2 anti-human IgA - FITC is a pepsin digest of goat anti-human IgA that reacts with the heavy chain of human IgA as demonstrated by flow cytometry. May also react with IgA from other species. Applications: Secondary antibody for flow cytometry, Immunohistochemistry or direct immunofluorescent staining of IgA+ human B lymphocytes. WORKING DILUTIONS Flow cytometry: 500 ng/106 cells Immunofluorescence: ≤ 1 μg/106 cells 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 flow cytometry. May also react with IgA from other species.
