Description: Recombinant Human Cystatin C Protein is produced by mammalian expression system and the target gene encoding Ser27-Ala146 is expressed. Form: Lyophilized from a 0.2 μm filtered solution of 10mM PB, 200mM Nacl, pH6.5. Gene Symbol: CST3 Alternative Names: Cystatin-C; Cystatin-3; Gamma-trace; Neuroendocrine basic polypeptide; Post-gamma-globulinEntrez Gene (Human): 1471SwissProt (Human): P01034Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : SSPGKPPRLV GGPMDASVEE EGVRRALDFA VGEYNKASND MYHSRALQVV RARKQIVAGV NYFLDVELGR TTCTKTQPNL DNCPFHDQPH LKRKAFCSFQ IYAVPWQGTM TLSKSTCQDA Directions 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.
