Boc-Val-Pro-Arg-AFC (Thrombin substrate fluorogenic) - 5 mg

Molecular Weight: 681.31Salt Form: AcetatePurity: >96%Sequence (3-letter): Boc-Val-Pro-Arg-AFCSequence (1-letter): Boc-VPR-AFCStorage: -20 °C or belowBoc-Val-Pro-Arg-AMC is a fluorogenic substrate for alpha-thrombin (Km = 21 μM kcat = 109 s-1) and the thrombin-staphylocoagulase complex (Km = 25 μM kcat = 89 s-1). The substrate is also cleaved by trypsin tryptase from rat mast cells Kex2 endoprotease and acrosin and spermosin (trypsin-like enzymes from sperm of the ascidian Halocynthia roretzi).Activity is quantified by release of free fluorescent 7-amino-4-methylcoumarin (AMC) which excites at 360-380 nm and emits at 440-460 nm.
