Endotoxin Level: Predicted Molecular Mass:33 kDa SDS-PAGE:46-50 kDa, reducing conditions Activity:Measured by its ability to cleave a flourogenic peptide substrate Pro-Phe-Arg-7-amido-4-methylcoumarin (PFR-AMC). The specific activity is >330 pmol/min/µg, as measured under the described conditions. Formulation:Supplied as a 0.2 µm filtered solution in MES, NaCl, CaCl₂ and Brij-35.See Certificate of Analysis for details. Molecule Information: Testisin/Prss21 Aliases: Prss21; TEST1 Entrez Gene IDs: 10942 (Human); 57256 (Mouse) Background: Tryptases Tryptases are serine proteases with trypsin-like specificity. Together with chymases and Cathepsin G, tryptases are important players in mast cell mediation of inflammatory and allergic responses. Tryptase beta-1, also known as mast cell protease 7 (MCPT7), exhibits anticoagulant activity due to its ability to degrade fibrinogen in the presence of a diverse array of protease inhibitors in plasma. Tryptase epsilon, also known as brain-specific serine protease 4 (BSSP-4) and brain serine protease 2 (BSP-2), is encoded by the PRSS22 gene and preferentially expressed in epithelium-rich tissues such as lung and eye. Tryptase gamma-1, also called transmembrane tryptase, is encoded by TPSG1, one of many serine protease genes clustered on human chromosome 16p13.3.
