Anti-PCNA Antibody

Proliferating cell nuclear antigen (PCNA) belongs to the DNA sliding clamp family and is comprised of three identical monomers forming a heterodimer. Due to its unique structure, PCNA is able to increase the processivity of DNA polymerase delta by using its outer domains to be involved in protein-protein interaction while still tethered to and freely sliding along the DNA. PCNA is a critical regulatory component in the onset of leading strand DNA replication and the termination of lagging strand synthesis. Studies have also indicated a role for PCNA in the recruitment and regulation of MMR pathway repair proteins. PCNA is also able to interact with a wide variety of cell cycle proteins and serves to coordinate several proteins participating in DNA processes, such as apoptosis.

Other homologies: Bovine, rabbit, canine, and panda (99% sequence homology).

Use Anti-PCNA Antibody (Rabbit Polyclonal Antibody) validated in WB, ICC to detect PCNA also known as proliferating cell nuclear antigen, cyclin, DNA polymerase delta auxiliary protein, Cyclin.

Western Blot Analysis: 1 µg/mL from a previous lot detected PCNA on 10 µg of NIH/3T3 and PC12 cell lysates.

Immunocytochemistry Analysis: 1:500 dilution from a previous lot detected PCNA in A431 cells.

Evaluated by Western Blot in A431 cell lysate.

Western Blot Analysis: 1 µg/mL of this antibody detected PCNA on 10 µg of A431 cell lysate.

~ 35 kDa observed. PCNA has a predicted molecular weight of 29 kDa, however, it can be monoubiquitinated, resulting in a ~ 35 kDa band.
