• Cat.No.: BirA-3247E
• Product Overview: Recombinant E. coli BirA protein(P06709) (Met1–Lys321) was expressed in E.coli, fused with an N-terminal polyhistidine-tagged MBP tag at the N-terminus.

Specification

• Species: E.coli
• Source: E.coli
• Tag: His&MBP
• Protein Length: 1–321 aa
• Form: Lyophilized from sterile 50mM Tris, 100mM NaCl, 10% Glycerol, pH 8.0.
• Molecular Mass: The recombinant E.coil BirA/MBP fusion protein consists of 713 amino acids and has a calculated molecular mass of 78.3 kDa. It migrates as an approximately 64-68 kDa band in SDS-PAGE under reducing conditions.
