Description：Recombinant Human CST3 Protein is produced by mammalian expression system and the target gene encoding Ser27-Ala146 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 10mM PB, 200mM Nacl, pH 6.5.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：SSPGKPPRLV GGPMDASVEE EGVRRALDFA VGEYNKASND MYHSRALQVV RARKQIVAGV NYFLDVELGR TTCTKTQPNL DNCPFHDQPH LKRKAFCSFQ IYAVPWQGTM TLSKSTCQDA VDHHHHHHDirections 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：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.
