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 7.25 Gene Symbol: CYB5A Alternative Names: CYB5; Cytochrome b5; Microsomal cytochrome b5 type A; MCB5Entrez Gene (Human): 1528SwissProt (Human): P00167Purity : 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 MAED 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 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.
