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. |
Synonyms | kallikrein-related peptidase 11, TLSP, hippostasin, Kallikrein-11, hK11, Hippostasin, Trypsin-like protease, Serine protease 20, PRSS20, MGC33060, EC 3.4.21. |
Source | HEK293-F Cells. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | The KLK11 protein was lyophilized from a 0.2 |
Solubility | It is recommended to reconstitute the lyophilized KLK11 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Stability | Lyophilized KLK11 althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution KLK11 should be storedat 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. |

Purity | Greater than 95.0% as determined by SDS-PAGE. |
Biological Activity | KLK11 specific activity is greater than 2200 pmoles/min/μg when measure with 100uM colormetric peptide substrate (D-Val-Leu-Lys-ThioBenzyl ester) and 1 μg of activated enzyme. The reaction is carried out in a volume of 100μL containing 50mM Tris, 1M NaCl, 10mM EDTA, 0.1mM DTNB (5,5’Dithio-bis(2-nitrobenzoic acid)), pH8.5 at 37°C. Cleavage of the peptide substrate can be measured at a wavelength of 405nm and quantified using the extinction coeffiecient 13,260M-1cm-1. |
