Cat no: S7972-86C-AP

Stefin B (STFB, CPI-B, CST6, Cystatin B, Cystatin-B, CSTB, EPM1, Liver Thiol Proteinase Inhibitor, PME, Unverricht Lundborg Type) (AP)

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 kininogens. This gene encodes a stefin that functions as an intracellular thiol protease inhibitor. The protein is able to form a dimer stabilized by noncovalent forces, inhibiting papain and cathepsins l, h and b. The protein is thought to play a role in protecting against the proteases leaking from lysosomes. Evidence indicates that mutations in this gene are responsible for the primary defects in patients with progressive myoclonic epilepsy (EPM1). \n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilutions:\nELISA: 1ug/ml-3ng/ml. The detection limit for S7972-86C is ~1ng/ml as a capture antibody.\nWestern Blot: 1:500-1:1000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Do not freeze alkaline phosphatase conjugates which could result in a substantial loss of enzymatic activity. Light sensitive. Aliquots are stable for 6 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
