Purine Nucleoside Phosphorylase/PNP Knockout 293T Cell Lysate Summary

• Preparation Method: Knockout achieved by using CRISPR/Cas9,1 bp insertion in exon 2
• Gene: PNP

Applications/Dilutions

• Dilutions:
  • Western Blot
• Application Notes: You will receive 1 vial (100ug) of knockout cell lysate and 1 vial (100ug) of Parental cell lysate. Lysate can be diluted with 1X SDS sample buffer and will be stable at -20 degrees C for 12 months. Minimize freeze-thaw cycles.

Packaging, Storage & Formulations

• Storage: Store at -20C short term. Aliquot and store at -80C long term. Avoid freeze-thaw cycles.
• Buffer: 0.1 mg cell homogenate lyophilized in RIPA buffer made with double-knockout cell lines.
• Concentration: LYOPH
• Reconstitution Instructions: To use as WB negative control, spin down briefly and resuspend in 100 uL 1xSDS sample buffer (2% SDS, 60 mM Tris-HCl pH 6.8, 10% Glycerol, 0.02% Bromophenol blue, 60 mM beta-mercaptoethanol). Boil the lysate for 3 - 5 minutes before loading it onto gel.

Lysate Details for Array

• Type: Knockout 293T Cell
• Life Stage: Embryonic

Notes

Powered by EDIGENE.
Validation of antibody specificity is critical and verification of antibody performance against knockout samples is one way to guarantee that an antibody recognizes a specific target. Novus' KO cell lysate can be used as a negative control for western blots and to confirm the specificity of antibodies.

Background

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]
