Anti-CST1, ID (Cystatin-SN, Cystain-SA-I, Cystatin-1, Salivary Cystatin-SA-1)

Human saliva appears to contain several cysteine proteinase inhibitors that are immunologically related to cystatin S but that differ in their specificity due to amino acid sequence differences. Cystatin SN, with a pI of 7.5, is a much better inhibitor of papain and dipeptidyl peptidase I than is cystatin S, although both inhibit ficin equally well. Applications: Suitable for use in ELISA, Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:20,000, Immunofluorescence: 1:100-1:500, Immunohistochemistry (Formalin fixed paraffin embedded): 5ug/ml, Optimal dilutions to be determined by the researcher.
