Proliferating cell nuclear antigen serves as an essential coordinator of DNA replication and repair, functioning as a sliding clamp that tethers DNA polymerase delta to the template strand during S phase. Beyond its canonical role in replication, PCNA participates in numerous cellular processes including chromatin remodeling, cell cycle control, and DNA damage response pathways. This positions PCNA as a widely utilized marker for cellular proliferation, making it invaluable across cancer biology, cell cycle research, and studies investigating genomic stability.
This recombinant monoclonal antibody, clone 3E8, offers the reproducibility that demanding experimental workflows require. Because recombinant antibodies are produced from defined genetic sequences rather than hybridoma supernatants, researchers benefit from consistent performance across different lots, eliminating the variability that can compromise longitudinal studies or multi-site collaborations. The mouse IgG2a isotype and affinity-chromatography purification further ensure reliable specificity against human PCNA.
Flow cytometry validation demonstrates robust intracellular detection in JK cells, a human Jurkat-derived lymphoblastic line, with effective staining achieved at dilutions ranging from 1:20 to 1:500. The validation protocol employed formaldehyde fixation followed by Triton X-100 permeabilization, providing a tested framework for researchers establishing their own intracellular staining workflows. Clear separation between the antibody signal and isotype control confirms specific target recognition with minimal background.
Whether investigating proliferative indices in tumor samples, examining cell cycle dynamics, or using PCNA as a nuclear loading control, this antibody supports diverse experimental approaches validated for ELISA and flow cytometry applications. Its utility spans epigenetics research, nuclear signaling studies, and broader cell biology investigations where reliable proliferation assessment is essential.
