特徴

• 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.
• The cystatin locus on chromosome 20 contains the majority of the type 2 cystatin genes and pseudogenes.
• CST4 is located in the cystatin locus and encodes a type 2 salivary cysteine peptidase inhibitor.
• Cystatin S is an S-type cystatin, based on its high level of expression in saliva, tears and seminal plasma.
• The specific role in these fluids is unclear but antibacterial and antiviral activity is present, consistent with a protective function.
• Applications:Suitable for use in Western Blot and ELISA.
• Other applications not tested.
• Recommended Dilution:Western Blot: 1:500-1:2000ELISA: 1:5000-1:20,000Optimal dilutions to be determined by the researcher.
