Single band by SDS-PAGE

General description

Recombinant, human purine nucleotide phosphorylase expressed in E. coli without tags. Purine nucleoside phosphorylase catalyzes the phosphorolysis of N-ribosidic bonds of purine nucleosides and deoxynucleosides. This reaction is reversible. The human enzyme is a target for therapeutic immune response intervention.

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.
