IgA is the most abundant immunoglobulin in body fluids and the second most abundant immunoglobulin in plasma, found at a concentration of 0.4 to 2.2mg/ml. It plays a very important role in the first specific defense against natural infection. Secretory IgA differs from serum IgA in that it contains two additional peptides: the secretory component and the J chain.

Suitable for use in Immunohistochemistry and FLISA. Other applications have not been tested.

Immunohistochemistry: Frozen and Paraffin sections Optimal working dilutions to be determined by researcher.

NS1 myeloma cells with spleen cells from Balb/c mice.
