Description

General description

Recombinant, human purine nucleotide phosphorylase expressed in E. coli without tags. Purine nucleoside phosphorylase catalyzes the phosphorlysis of N-ribosidic bonds of purine nucleosides and deoxynucleosides in a reversible reaction. Human PNP is a target for therapeutic T-cell immune response intervention. Useful in the detection of inorganic phosphate from biochemical reactions.

Physical form

In 50 mM Tris-HCl, pH 7.6.

Analysis Note

Single band by SDS-PAGE
