Anti-OTUB1 Antibody

This rabbit polyclonal antibody targets OTUB1, a cysteine-dependent deubiquitinase of the ovarian tumor (OTU) family that selectively cleaves K48- and K63-linked polyubiquitin chains. Distributed by Antibodies.com, the reagent is validated for Western blot and immunofluorescence workflows on human samples, supporting studies of DNA damage signaling, p53 pathway regulation, and the TGF-β axis where OTUB1 activity has documented roles in tumor biology and viral immune evasion. The preparation is supplied as 100 µl of unconjugated antiserum, suitable for standard immunoblotting loading volumes and for indirect fluorescence labeling with a user-selected secondary reagent. Store the vial at -20 °C in small aliquots to limit freeze-thaw cycles, and protect from light during handling to preserve antibody activity across multiple experiments. For research use only.
