Rabbit Antiserum anti-Human Secretory Component, free-unconj., MinX none

Tested in immunoelectrophoresis, double radial immunodiffusion and ELISA against a panel of appropriate secretions and purified Ig isotypes. The antiserum reacts with the free SC present in human secretions. In immunoelectrophoresis against human milk, using a high electro-endosmosis agar plate, free SC is precipitated in the alph-2 region. The antiserum does not react with sIgA, or with any other secretory or plasma protein.

Delipidated, heat inactivated, lyophilized, stable whole antiserum. No preservative added. Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal rabbit serum. No foreign proteins added. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water.
