描述：

PCNA (D3H8P) XP^® Rabbit mAb可以识别内源性总的PCNA蛋白。单克隆抗体由合成肽段免疫动物产生，该肽段与人PCNA蛋白的羧基端一致。增殖细胞核抗原（PCNA）是DNA滑动钳蛋白家族的一员，协助DNA复制（1）。晶体结构数据提示PCNA形成的同源三聚体环可以环绕包围DNA双螺旋（2）。很多涉及到DNA复制，修复和细胞周期调控的蛋白都是与PCNA结合而不是直接地和DNA结合，因此可以促进DNA的快速处理（reviewed in 3）。PCNA蛋白表达是一个广泛认可的增殖信号，PCNA（PC10）mouse mAb已经被上百种研究用于衡量PCNA的表达量。

Specificity / Sensitivity

PCNA (D3H8P) XP^® Rabbit mAb recognizes endogenous levels of total PCNA protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human PCNA protein.

Background

Proliferating cell nuclear antigen (PCNA) is a member of the DNA sliding clamp family of proteins that assist in DNA replication (1). Crystal structure data suggests that a PCNA homotrimer ring can encircle and slide along the DNA double helix (2). Multiple proteins involved in DNA replication, DNA repair, and cell cycle control bind to PCNA rather than directly associating with DNA, thus facilitating fast processing of DNA (reviewed in 3). PCNA protein expression is a well-accepted marker of proliferation and PCNA (PC10) mouse mAb has been used to assess PCNA levels in hundreds of scientific studies.
