Kallikreins are a subgroup of serine proteases containing various physiological functions. kallikreins are involved in carcinogenesis and several have potential as novel cancer and other disease biomarkers. KLK4 is one of the fifteen kallikrein subfamily members localized in a cluster on chromosome 19. In some tissues its expression is hormonally regulated. KLK4 is involved in the degradation of enamel proteins.
Sterile Filtered White lyophilized (freeze-dried) powder.
The KLK4 protein was lyophilized from a 0.2
It is recommended to reconstitute the lyophilized KLK4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized KLK4 althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution KLK4 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.
Greater than 95.0% as determined by SDS-PAGE.
