Anti-PUNP antibodies are used in antigen-specific immunodetection in biological samples. The target PUNP is a known alias name of the protein purine nucleoside phosphorylase, encoded by the PNP gene in humans. This 289-amino acid residue protein is known to catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. It is localized to the cytoplasm of the cell. In terms of tissue expression, it is reported to be expressed in red blood cells; overexpressed in red blood cells (cytoplasm) of patients with hereditary non-spherocytic hemolytic anemia of unknown etiology. Other synonyms for PUNP include NP and PRO1837. Indicated applications for PUNP antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
