PURIFIED POLYCLONAL HUMAN SECRETORY IgA

BP148

For In-vitro Research use

REAGENT:

PREPARATION: Purified human Secretory IgA is prepared from human milk obtained from a suitable individual donor. It is purified by ion exchange chromatography and gel filtration. The purified protein is confirmed to be essentially free of other host proteins by immunoelectrophoresis and SDS-PAGE. The purified protein is dialyzed into stabilizing buffer containing preservatives and 0.2m m filtered. The concentration of the purified protein is determined using a Secretory IgA radial immunodiffusion plate (The Binding Site Product Code RN148).

FORM: Purified human secretory IgA.
Protein Concentration: 0.5mg/mL
Buffer: TRIS buffered saline pH 7.4
Preservatives: 0.1% Sodium Azide + 0.1% E-amino-n-caproic acid + 0.01% benzamidine

CAUTION: This product contains 0.1% sodium azide as a preservative. Appropriate precautions should therefore be observed.
