IgA Secretory Component (ECM1, Extracellular Matrix Protein 1, Secretory Component p85, URBWD) (HRP)

This MAb reacts with a reduction-resistant epitope present in both free and SIgA bound Secretory Component. It does not react with the cell lines lacking secretory component. 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.||Applications: |Suitable for use in ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.||Recommended Dilution:|Western Blot: 0.5-1ug/ml|Immunoprecipitation: 1-2ug/500ug protein lysate|Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT |(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)|Optimal dilution for a specific application should be determined.||Positive Control:|Stomach, Lung, or breast tumor||Storage and Stability:|Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. |For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.||Note: Applications are based on unconjugated antibody.
