Background: SERPINB3, also known as SCCA-1, belongs to the serpin family. Serpins are a group of proteins with similar structures that were first identified as a set of proteins able to inhibit proteases. The acronym serpin was originally coined because many serpins inhibit chymotrypsin-like serine proteases. SERPINB3 is expressed in some hepatocellular carcinoma (at protein level). Its expression is closely related to cellular differentiation in both normal and malignant squamous cells. It seems to also be secreted in plasma by cancerous cells but at a low level. SERPINB3 significantly attenuates apoptosis by contrasting cytochrome c release from the mitochondria and by antichemotactic effect for NK cells. It may act as a protease inhibitor to modulate the host immune response against tumor cells and may be involved in the malignant behavior of squamous cell carcinoma cells.
Concentration:
Activity: Measured by its ability to inhibit active Cathepsin L cleavage of a fluorogenice peptide substrate Z-LR-AMC, R&D Systems, Catalog # ES008.The IC50 is < 5 nM.
Sequence: Asn 2-Pro 390
Purity: > 97 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4, 20% glycerol, 3mM DTT
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: Please refer to the printed manual for detailed information.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
Calculated MW: 46.7 kDa
ObservedMW: 43 kDa
