Greater than 90.0% as determined by SDS-PAGE. |
Description |
KLK13 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 284 amino acids (17-277 a.a) and having a molecular mass of 31.3kDa.KLK13 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
Protein Background |
Kallikreins are a subgroup of serine proteases having various physiological functions. Many kallikreins are implicated in carcinogenesis and some have potential of becoming novel cancer and other disease biomarkers. Kallikrein-13 (KLK13) is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. KLK13 gene expression is regulated by steroid hormones and may be useful as a marker for breast cancer. |
Expression host |
Escherichia Coli. |
Synonyms |
Kallikrein-13, KLK-L4, KLKL4, Kallikrein-like protein 4. |
Reagent Appearance |
Sterile Filtered colorless solution. |
Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
