Product Description

Product is the lyophilized powder of human secretory IgA and buffer salts.

Application Notes

Purified IgA secretory may be used as a reference antigen, standard, blocking agent or coating protein in a variety of immunoassays including ELISA, dot immunobinding, immunoblotting, immunodiffusion and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solidphase immunoadsorbents. IgA from human colostrum was used as a standard in ELISA (1 mg/mL) and gel electrophoresis.

Analysis Note All human products should be treated as potentially infectious. Source material from which this product was derived was found negative when tested in accordance with current FDA required tests. No known test methods can offer assurance that products derived from human blood will not transmit infectious agents. The total protein is determined using the Biuret procedure, with bovine albumin as the standard. Each vial is overfilled by approximately 5 percent so that a minimum of 5 mg of human secretory IgA is obtained upon reconstitution
Antibody Type Polyclonal Antibody
