Kallikrein-1 蛋白, Human (244a.a, HEK293, His, solution)

Kallikrein-1 protein cleaves bonds in kininogen to release Lys-bradykinin. It also cleaves Neisseria meningitidis NHBA in saliva during microbial infection.Kallikrein-1 Protein, Human (244a.a, HEK293, His, solution) is the recombinant human-derived Kallikrein-1 protein, expressed by HEK293 , with C-6*His labeled tag.

Kallikrein-1 蛋白通过裂解激肽原中的 Met-Lys 和 Arg-Ser 键发挥作用，导致 Lys-缓激肽的释放。在微生物感染的情况下，它在裂解唾液中的脑膜炎奈瑟氏菌 NHBA 方面发挥着作用，而奈瑟氏菌是鼻咽粘膜的专性共生体。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
