The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions. CST5 may play a protective role against proteinases present in the oral cavity.
Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed.
Target:
The synthetic peptide sequence used to generate the antibody AP8984c was selected from the Center region of human CST5. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
