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

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 Immunofluorescence, Flow Cytometry (Not Tested), FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.||Recommended Dilution:|Flow Cytometry (Not Tested): 0.5-1ug/million cells |Immunofluorescence: 1-2ug/ml |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.Applications: |Suitable for use in Immunofluorescence, Flow Cytometry (Not Tested), FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.||Positive Control:|Stomach, Lung, or breast tumor||Storage and Stability:|May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. APC is light sensitive.||Note: Applications are based on unconjugated antibody.
