PCNA (Proliferating Cell Nuclear Antigen), plays a central role in coordinating the association of replication factors during DNA replication as well as during recognition and repair of DNA damage. PCNA forms a toroidal, ring-shaped structure of 90 kD by the symmetric association of three identical monomers. The ring encircles the DNA, acts as a platform upon which polymerases and other proteins dock to perform various DNA metabolic processes, and functions as a DNA polymerase-delta co-factor. The association of proteins with the replication fork through interactions with PCNA is regulated by several mechanisms. PCNA interacts with numerous proteins to facilitate DNA replication and repair, epigenetic processes and sister chromatid cohesion. PCNA has its highest expression during G1and S-phases, and its expression decreases in G2 and M-phases. This marker is also present in the early G0 phase because of its long half-live of 8-20 h. PCNA is a nuclear nonhistone protein that is necessary for DNA synthesis and is an accessory protein for DNA polymerase alpha, which is elevated during the G1/S phase of the cell cycle. Several studies have been performed to evaluate cell proliferation using PCNA and Ki-67 in different tumors of various origins; compared with PCNA, Ki-67 has been shown to be more sensitive and specific in the various tumors.

FAQs for PCNA Antibody (NB500-106). (Showing 1 - 3 of 3 FAQs).

  1. I am looking into preparing an exercise for an undergraduate lab that would immunostain drosophila testes. I think that PCNA Antibody (PC10) (cat # NB500-106) would be used as the primary antibody. What would you suggest to be used for the secondary? We have a fluorescent microscope and have used FITC in the past for some of our labs. Just trying to give the students a chance to visualize stained testes.
    • After looking at the applications of this antibody, I just found that we have not established this antibody for its Immunofluorescence application in our lab yet, however, as it has been tested successfully in IHC-P by our lab and by other researchers; there is a very strong chance that it should work in IHC-P/IF application also. If you would be interested in testing this novel application, please take a look at our Innovator's Reward Program. Regarding your specific query on secondary antibody, our FITC conjugated Mouse IgG antibody with catalog # NB720-F would be a perfect choice for primary PCNA Antibody (PC10) with catalog # NB500-106.
  2. Do you have data/information on the use of this antibody for Drosophila (mentioned on your website as possible target species)? I would like to know if any specific treatment is needed with regard to this type of sample and the use of the antibody in WB, IP in ICC.
    • This particular product is a widely licensed monoclonal clone. We obtained validation of its ability to detect the Drosophila protein from the following publication: PMID 22253867. You should be able to follow our general protocols for WB, IP, and ICC to detect this protein in their samples. Please see the following link for protocols.
  3. Can you please tell me the specific region of immunogen of this product?
    • This antibody was raised against whole rat PCNA protein fused to Protein A. As we have not yet epitope mapped this product, we do not know the exact immunogen recognized by this antibody.
