Description
Description: CD33 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (18-259 a.a.) and fused to a 239 aa hIgG-His Tag at C-terminus containing a total of 484 amino acids and having a molecular mass of 54kDa. CD33 shows multiple bands between 50-70kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
Introduction: Tryptase alpha/beta-1 (TPSAB1) is a tryptase which is the key neutral protease present in mast cells and is discharged upon the coupled activation-degranulation response of this cell type. TPSAB1 is enzymatically active only as a heparin-stabilized tetramer, and is resistant to all known endogenous proteinase inhibitors. TPSAB1 is implicated as a mediator in the pathogenesis of asthma and other allergic and inflammatory disorders
