Cat#:RP-4240H;Product Name:Recombinant Human KRT19 Protein;Synonym:Keratin type I cytoskeletal 19, Cytokeratin-19, CK-19, Keratin-19, K19, KRT19, CK19, K1CS, MGC15366.;Description:Cytokeratin 19 Protein produced in E.coli is a single, non-glycosylated polypeptide chain having a molecular mass of 44,098 Dalton. The KRT19 is purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by SDS-PAGE.;Formulation:The protein (1mg/ml) was lyophilized after from a sterile solution containing 30mM Tris-HCl pH-8, 9.5M urea, 2mM DTT, 2mM EDTA and 10mM methylammonium chloride.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized KRT19 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized KRT19 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution KRT19 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.;
