Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 1-461 (end)
Applications: Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Assay Conditions: 50 mM Tris-HCl, pH 8.5, 150 mM NaCl, 10 mM CaCl2, 0.01% Brij-35, 100 µM substrate, and various amounts of Activated Protein C. Incubate for 10 minutes at room temperature. Fluorescence intensity is measured at exc380/em460.
Description: Human activated protein C, also known as PROC, APC, or active coagulation factor XIV, (GenBank Accession No. NM_000312), a.a. 1 - 461 (end) with C-terminal His-tag, expressed in an HEK293 cell expression system. Note: Protein is secreted and converted to the active form with disulfide link (light chain a.a. 43-199, heavy chain a.a. 212-461). The signal peptide (a.a. 1-32), propeptide (a.a. 33-42), and activation peptide (a.a. 200-211) are cleaved. MW = ~60 kDa, ~42 kDa, ~20 kDa under reducing conditions.
