Recombinant Human Plasma Kallikrein/KLKB1 Protein

Cat. No.: rp167404
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. His Tag ? His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. ≥90%(SDS-PAGE)

Overview

Function
Participates in the surface-dependent activation of blood coagulation. Activates, in a reciprocal reaction, coagulation factor XII/F12 after binding to negatively charged surfaces. Releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin.
