Anti-PCNA Antibody

Mouse monoclonal antibody targeting Proliferating Cell Nuclear Antigen (PCNA), a 36 kDa nuclear auxiliary protein for DNA polymerase delta that is widely used as a proliferation marker in tumor biology and cell cycle research. The Antibodies.com IgG2b isotype reagent is supplied unconjugated in a 100 µl vial, supporting western blot, immunoprecipitation, and immunocytochemistry workflows in Human, Mouse, Monkey, and Rat samples. Researchers apply this antibody to track S-phase entry, validate DNA replication competence, and assess proliferative indices in cancer cell lines and tissue sections. The unconjugated format gives flexibility in pairing with fluorescent or HRP-conjugated secondary antibodies. For storage, refrigerate the vial and aliquot to limit freeze-thaw cycles, which preserves epitope-binding activity over multiple experiments.
