Description：Recombinant Human CYB5A Protein is produced by E.coli expression system and the target gene encoding Met1-Asp134 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, 0.1mM EDTA, pH 7.25Gene Symbol：CYB5AAlternative Names：CYB5; Cytochrome b5; Microsomal cytochrome b5 type A; MCB5 Entrez Gene (Human)： 1528; SwissProt (Human)： P00167; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MAEQSDEAVK YYTLEEIQKH NHSKSTWLIL HHKVYDLTKF LEEHPGGEEV LREQAGGDAT ENFEDVGHST DAREMSKTFI IGELHPDDRP KLNKPPETLI TTIDSSSSWW TNWVIPAISA VAVALMYRLY MAEDDirections 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.
