Anti-PSME3 Antibody - Identical to Abcam (ab180829)

Produced as a rabbit polyclonal IgG raised against the PSME3 immunoproteasome regulator (also known as REGγ and PA28γ), this unconjugated reagent from Antibodies.com is supplied at 200 µl per vial and supports Western blot and immunofluorescence workflows in human, mouse, and rat samples. The reagent is identical to the well-characterised reference antibody ab180829 and is calibrated for detection of endogenous PSME3 levels in cell lysates and fixed-cell preparations. PSME3 directs ATP- and ubiquitin-independent processing by the 20S proteasome and influences cell-cycle progression, stress responses, and turnover of tumor suppressors such as p53, p21 and regulators within the MDM2 axis, so reliable reagents for tracking its abundance are valuable across apoptosis, DNA-damage, and cancer-research programmes. Storage at -20 °C in single-use aliquots preserves activity across repeated freeze-thaw cycles and protects against loss of titer when the vial is opened for routine blotting or imaging experiments.
