Description：Recombinant Human CALCA Protein is produced by E. coli expression system and the target gene encoding Tyr58-Asn141 is expressed with a 6His tag at the C-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, 50% Glycerol, pH 7.4.Gene Symbol：CALCAAlternative Names：CALC1; Calcitonin Entrez Gene (Human)： 796; SwissProt (Human)： P01258; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：YVQMKASELE QEQEREGSSL DSPRSKRCGN LSTCMLGTYT QDFNKFHTFP QTAIGVGAPG KKRDMSSDLE RDHRPHVSMP QNANVEHHHH HHDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
