PNP blocking peptide
PNP Immunizing Peptide
NCBI and Uniprot Product Information
NCBI Description
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. [provided by RefSeq, Jul 2008]
Uniprot Description

Product Notes
The PNP pnp (Catalog #AAA427950) is a Blocking Peptide and is intended for research purposes only. The product is available for immediate purchase. The PNP Immunizing Peptide reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. The amino acid sequence is listed below: C-SGQNPLRG PNDE. It is sometimes possible for the material contained within the vial of "PNP, Blocking Peptide" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
