Anti-PCNA (Proliferating Cell Nuclear Antigen) recognizes polymerase delta accessory protein (Mr 36 kDa).1,3 This auxiliary protein is also known as cyclin and experiments strongly suggest that PCNA is essential for cellular DNA synthesis.2,3
Anti-PCNA staining is almost entirely confined to the nucleus and may show a diffuse or granular pattern or a mixture of both. Dominant PCNA expression begins during late G1 phase and is present through S phase of the cell cycle.
Known Species Cross Reactivity: Ms+, Hu+, Rt+, All vertebrate and insect species tested
Rat PCNA made in the protein A vector pR1T2T
