  This recombinant protein was expressed from a DNA sequence
encoding the human KLK8 isoform 1 (O60259-1) (Met 1-Gly 260)
fused to a polyhistidine tag at the C-terminus.  Activity:
Measured by its ability to inhibit thrombin cleavage of a
fluorogenic peptide substrate Boc-VPR-AMC. The specific activity
is >500 pmoles/min/µg.     This protein is manufactured by Sino
Biological Inc.
