Description：Recombinant Human Cystatin C Protein is produced by E.coli expression system and the target gene encoding Gly26-Ala146 is expressed.Form：Lyophilized from a 0.2 μm filtered solution of 20mM HEPES, 150mM NaCl, pH7.4.Gene Symbol：CST3Alternative Names：Cystatin-C; Cystatin-3; Gamma-trace; Neuroendocrine basic polypeptide; Post-gamma-globulin Entrez Gene (Human)： 1471; SwissProt (Human)： P01034; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：GSSPGKPPRL VGGPMDASVE EEGVRRALDF AVGEYNKASN DMYHSRALQV VRARKQIVAG VNYFLDVELG RTTCTKTQPN LDNCPFHDQP HLKRKAFCSF QIYAVPWQGT MTLSKSTCQD ADirections 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 ddH2O. 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：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
