Product Overview
Clone DO-16 is a rabbit monoclonal antibody that recognizes DNA sliding clamp PCNA in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 28.8 kDa, and the supplier reports an observed band at about 36 kDa.
PCNA (proliferating cell nuclear antigen) is a ring-shaped DNA clamp that encircles DNA and tethers polymerases δ and ε for processive replication. It also serves as a platform for many repair and damage-tolerance factors and is a classic marker of proliferating cells.

Samples with a confirmed band (WB): human HeLa cells, human HepG2 cells, human U-937 cells, human 293T cells, mouse spleen tissue, rat RAW264.7 tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:3000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): U2OS cells.
Immunogen
Synthetic peptide based on the sequence of human PCNA.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places DNA sliding clamp PCNA in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
