Catalogue Number 152584
Applications FACS IHC IF IP WB
Antigen/Gene or Protein Targets Proliferating cell nuclear antigen, (PCNA), also known as cyclin or polymerase delta accessory protein
Reactivity Human, Insect and Saccharomyces
Relevance Monoclonal antibody which binds a widely conserved proliferating cell nuclear antigen, present in all proliferating cells as a marker of DNA synthesis, with neoplastic diagnostic and prognostic value.

Background and Research Application
PCNA, also known as polymerase delta auxiliary protein, is essential for DNA replication and is involved in DNA excision and mismatch repair pathways. PCNA is required for cellular DNA synthesis, and in vitro replication of SV40 DNA. It helps to co-ordinate the leading and lagging strand synthesis at the replication fork. PCNA binds to the CDK inhibitor p21, the structure-specific endonucleases Fen1 and XPG, and DNA cytosine 5-methyltransferase (MCMT). PCNA is potentially a therapeutic target in cancer therapy and a useful marker for identifying the proliferation status of tumour tissue (i.e. relevant to prognosis). This antibody can be used to grade different neoplasms, e.g. astrocytoma. It can be of diagnostic and prognostic value.
This antibody was first published in 1990 when various monoclonal antibodies for PCNA were created to characterise and understand the function of this protein within cellular DNA synthesis and proliferation.

Points of Interest
PCNA can be used as a marker for DNA synthesis and is widely conserved between species. Anti-PCNA can detect the varying levels of PCNA within cell cycle progression and DNA synthesis, through PCNA immunoprecipitation. It is capable of staining proliferating tumour tissue, beneficial for cancer research to investigate cell cycle progression, DNA replication and rates of proliferation. This antibody can recognise epitopes conserved from man to fission yeast, given PCNA amino acid sequences share homology and the gene is present in mammals and plant cells, within a similar gene being present in the baculovirus Autographa californica.
