Description：Recombinant Human CRYAA Protein is produced by E. coli expression system and the target gene encoding Met1-Ser173 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of PBS, 2mM EDTA, pH 8.0.Gene Symbol：CRYAAAlternative Names：CRYA1; HSPB4; Alpha-crystallin A chain; Heat shock protein beta-4; HspB4 Entrez Gene (Human)： 102724652; 1409; SwissProt (Human)： P02489; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MDVTIQHPWF KRTLGPFYPS RLFDQFFGEG LFEYDLLPFL SSTISPYYRQ SLFRTVLDSG ISEVRSDRDK FVIFLDVKHF SPEDLTVKVQ DDFVEIHGKH NERQDDHGYI SREFHRRYRL PSNVDQSALS CSLSADGMLT FCGPKIQTGL DATHAERAIP VSREEKPTSA PSSLEHHHHH HDirections 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.
