Secretory Component Antibody / ECM1 [clone SC05] (V2104)

Description

This antibody reacts with a reduction-resistant epitope present in both free and SIgA bound Secretory component. It does not react with the cell lines lacking this protein. The antibody is useful for studying the distribution and level of both free and bound secretory component. Secretory component is differentially expressed in epithelium, and the antibody is a popular marker for identifying subpopulations of epithelial cells and epithelial differentiation. The Secretory component antibody is a useful research tool for studying mucosal immunity, inflammation, remodeling, differentiation and tumorigenesis, all processes associated with differential secretory component expression.

Application Notes

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

Immunogen

Secretory component protein isolated from human colostrum was used as the immunogen.

Storage

Store the Secretory Component antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
