Description

Specificity

Clone PC10 recognizes an epitope on mouse PCNA.

Antigen Distribution

PCNA is a ubiquitous nuclear protein present in all cell cycle stages, with the highest expression in the early S phase. Anti-PCNA staining is almost entirely confined to the nucleus and may show a diffuse or granular pattern or a mixture of both.

Background

PCNA antibody, clone PC10, recognizes proliferating cell nuclear antigen (PCNA), also known as cyclin, a 36 kDa nuclear protein belonging to the DNA sliding clamp family. PCNA is a ring-shaped homotrimer that encircles and slides along DNA^{1, 2}. PCNA is an auxiliary protein of DNA polymerase δ and ε and tethers the polymerase catalytic unit to the DNA template for efficient DNA synthesis^3-6. PCNA also contributes to chromatin remodeling, DNA repair, sister chromatid cohesion, and cell cycle control⁷. Expression levels of PCNA are associated with proliferation and transformation, and PCNA is commonly used as a marker for proliferating cells^{8, 9}. Antibodies to PCNA are detected in sera from patients with systemic lupus erythematosus (SLE)¹⁰. In addition, PCNA is a reliable diagnostic and prognostic biomarker for cancer, as tumor cells express high levels of PCNA¹¹.
