Purity: > 90 % by SDS - PAGE Format: Liquid, In Phosphate buffered saline (pH7.4) containing 50% glycerol, 1mM DTT . NuBP2 is an adenosine triphosphate (ATP) and metal-binding protein that is required for the assembly of cyotosolic iron-sulfur proteins. This protein functions in a heterotetramer with nucleotide-binding protein 1 (NuBP1). Alternative splicing results in multiple transcript variants. Recombinant human NuBP2 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
