E. coli-derived recombinant human Cystatin B
Specificity
Detects human Cystatin B in Western blots and direct ELISAs. In Western blots, less than 5% cross-reactivity with recombinant human (rh) Cystatins A and S, recombinant mouse Cystatin B, rhFetuin A, and rhHPRG (Histidine-Proline-Rich Glycoprotein) is observed and approximately 5% to 10% cross-reactivity with rhCystatins C, D, E/M, SA, SN, and rhFetuin B is observed.

Background: Cystatin B
Cystatin B, also called stefin B or liver thiol proteinase inhibitor, is a member of family 1 of the cystatin superfamily (1). Like Cystatin A, it is an intracellular inhibitor regulating the activities of cysteine proteases of the papain family such as cathepsins B, H and L (2). Mutations in the Cystatin B gene is the cause of progressive myoclonus epilepsy (EPM1) (3). Because of its expression patterns, Cystatin B can be used as a marker for certain cancers, such as glioblastoma tumors (4). It readily forms amyloid fibrils in vitro (5). The human Cystatin B consists of 98 amino acid residues (3).
