KLK11, Human

(kallikrein-related peptidase 11, TLSP, hippostasin, Kallikrein-11, hK11, Hippostasin, Trypsin-like protease, Serine protease 20, PRSS20, MGC33060, EC 3.4.21.)

KLK11 is a multifunctional protease. KLK11 cleaves ''bz-Phe-Arg-4-methylcoumaryl-7-amide'', KLK11 is a kallikrein substrate, and weakly cleaves other substrates for kallikrein and trypsin. KLK11 cleaves synthetic peptides after arginine rather than lysine residues.

KLK11 Human Recombinant produced in HEK-293 cells is a single, glycosylated, polypeptide chain having a molecular weight of 25.6kDa though on SDS-PAGE migrates at about 41kDa due to the glycosilation. The KLK11 is purified by proprietary chromatographic techniques.

Purity: Greater than 95.0% as determined by SDS-PAGE.

Source: HEK293-F Cells.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation: The KLK11 protein was lyophilized from a 0.2µm filtered solution containing no additives or preservatives.

Storage:
Lyophilized KLK11 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution KLK11 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
