Background of Purine Nucleoside Phosphorylase/PNP
Purine nucleoside phosphorylase, PNP, PNPase or inosine phosphorylase (EC 2.4.2.1) is an enzyme that in humans is encoded by the NP gene. This gene encodes an enzyme which reversibly catalyzes the phosphorolysis of purine nucleosides. The enzyme is trimeric, containing three identical subunits. Mutations which result in nucleoside phosphorylase deficiency result in defective T-cell (cell-mediated) immunity but can also affect B-cell immunity and antibody responses. Neurologic disorders may also be apparent in patients with immune defects. A known polymorphism at aa position 51 that does not affect enzyme activity has been described. A pseudogene has been identified on chromosome 2.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human PNP ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Reproducibility
We ensure reproducibility by testing three samples with differing concentrations of Purine Nucleoside Phosphorylase/PNP in ELISA kits from four different production batches/lots.
