Lyophilized
Reconstitution
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.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, 0.1 mM EDTA, pH 7.25.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Stockage commentaire
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
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. Alternative Names: Cytochrome b5, Microsomal Cytochrome b5 Type A, MCB5, CYB5A, CYB5
