Recombinant Human CYB5A protein, His-tagged

Cat.No.: CYB5A-22H
Product Overview: Recombinant Human CYB5A(Met1-Asp134) fused with His tag at N-terminal was expressed in E. coli.
Description: Cytochrome b5 (CYB5A) is a membrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases. CYB5A contains one cytochrome b5 heme-binding domain and has two isoforms produced by alternative splicing. Isoform 1 is a sngle-pass membrane protein. Isoform 2 is located in cytoplasm. The defects in CYB5A can result in type IV hereditary methemoglobinemia.
Source: E. coli
Species: Human
Tag : His
Form: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, 0.1mM EDTA, pH 7.25.
Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Storage: Lyophilized protein should be stored at < -20 centigrade, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7 centigrade for 2-7 days.
Aliquots of reconstituted samples are stable at < -20 centigrade for 3 months.
Reconstitution: 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.
