Rabbit anti-PCNA Antibody, Affinity Purified，100UL，PLA0079-100UL，Sigma

General description

Proliferating cell nuclear antigen (PCNA), a single-copy gene, spans about 12 kb. This gene is located on human chromosome 20p13. PCNA is expressed at high levels in the thymus, bone marrow, fetal liver, and some cells of the small intestine and colon. It is located in the nucleus.

Immunogen

The epitope recognized by PLA0079 maps to a region between residues 75 and 125 of human proliferating cell nuclear antigen using the numbering given in SwissProt entry P12004 (GeneID 5111).

Application

Rabbit anti-PCNA Antibody, Affinity Purified has been used in:

• proximity ligation assay (PLA) (1:500)
• immunoblotting (1:2000)
• flow cytometry analysis

Biochem/physiol Actions

Proliferating cell nuclear antigen (PCNA) protein functions as an auxiliary factor of polymerase δ. It acts as a cofactor to polymerase ε, polymerase β, and translesion synthesis polymerases, such as η, κ, λ, and θ. In chronic lymphoid leukemia (CLL) patients, intracellular levels of PCNA protein can be used as a marker to identify clinical behavior and survival.

Physical form

Tris-citrate/phosphate buffer, pH 7 to 8 containing 0.09% Sodium Azide

Other Notes

PCNA (Proliferating Cell Nuclear Antigen) was first identified as a factor expressed in the nuclei of replicating cells. PCNA plays a role in both DNA synthesis and repair. PCNA functions as a processivity factor for DNA polymerase by acting as a DNA clamp that tethers the polymerase catalytic units to the DNA template. The structure of PCNA is that of a trimeric ring that encircles and slides along replicating DNA. PCNA interacts with and is regulated by several proteins involved in cell cycle control and check point processes.
