Human secretory component (free and bound)

Human Secretory Component. Tested in immunoelectrophoresis, double radial immunodiffusion and ELISA against a panel of appropriate secretions and purified Ig isotypes. The antiserum reacts with both bound secretory component (secretory IgA) and with the free SC present in human secretions. In immunoelectrophoresis against human milk, using a high electroendosmosis agar plate, free SC is precipitated in the alpha-2 region. The antiserum does not react with other molecular forms of IgA, or with any other secretory or plasma protein. Cross-reactivity Inter-species cross-reactivity is a normal feature of antibodies to serum proteins, since homo- logous proteins of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.

• Immunodiffusion

This product is intended for use in precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion to identify the presence secretory component in human serum or other body fluids and to determine its concentration.

Lyophilized antiserum

Use 1 ml of sterile Distilled water.

Short term: store at 4°C. Long term: store at -20°C. Avoid freeze-thaw cycles.
