Application Notes
This p14ARF antibody is used for Western blotting, where a band is seen at where a band is seen at ~16 kDa, representing p14ARF (p14ARF tends to run slightly higher than the theoretical MW of 14 kDa). Additional faint bands may be seen at ~32 and 47 kDa. WB application of this product is mentioned in publication with PMID: 21636682. In ICC/IF, nuclear focal staining was observed in HeLa cells.

The INK4a-ARF locus is comprised of two tumor suppressors, p16INK4a and p14ARF. These two proteins are encoded through differential splicing of alternative first exons. The p16INK4a (exon 1 alpha) protein inhibits the cyclin D-dependent kinases (CDK) that control the phosphorylation of the Rb protein and cell proliferation. The p14ARF gene product complexes with the MDM2 protein within the nucleus, thus modulating the activity of the p53 protein. P14ARF is a potent tumor suppressor in the presence of wild-type p53, while mutant p53 substantially reduces growth inhibition by p14ARF.

FAQs for p14ARF/CDKN2A Antibody (NB200-111). (Showing 1 - 2 of 2 FAQs).

  1. While looking for antibodies targeting human p14ARF, I found a question: Based on the information on UniProt, human p14ARF has the length of only 132 a.a. However, the immunogen of NB200-159 is described as... between residue 125 and the C-terminus (residue 173)...,...between residues 100-173... for NB110-59085, and...between residues 50-150... for NB200-111.
    • Since these antibodies were produced, UniProt has since truncated the protein sequence. These antibodies are still directed towards p14ARF and the immunogens will be updated on our website to the updated amino acid ranges. Since you won't be able to see this until this weekend or early next week, the immunogen for NB200-111 falls between amino acids 50 and 132. The immunogen for NB200-159 falls between amino acids 90 and 132 and the immunogen for NB110-59085 falls between amino acids 50 and 132.
  2. Do you measure the isotype purity of NB200-111? I realize this is antigen affinity purified, and will be almost completely IgG, but do you measure for IgA/M amount by chance?
    • We unfortunately do not measure isotype purity for our products.
