Description：Recombinant Human CST1 Protein is produced by Mammalian expression system and the target gene encoding Trp21-Ser141 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM MES, 150mM NaCl, pH 5.5Gene Symbol：CST1Alternative Names：Cystatin-SN; Cystain-SA-I; Cystatin-1; Salivary cystatin-SA-1 Entrez Gene (Human)： 1469; SwissProt (Human)： P01037; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：WSPKEEDRII PGGIYNADLN DEWVQRALHF AISEYNKATK DDYYRRPLRV LRARQQTVGG VNYFFDVEVG RTICTKSQPN LDTCAFHEQP ELQKKQLCSF EIYEVPWENR RSLVKSRCQE SVDHHHHHHDirections 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.
