Anti-COPS4 Antibody

Produced in rabbit as a polyclonal IgG raised against COPS4 (also called COP9 signalosome subunit 4, or CSN4), this unconjugated primary antibody from Antibodies.com is supplied at 50 µl and is validated for Western blot detection of the human, mouse, and rat target.

COPS4 is a core component of the COP9 signalosome, an eight-subunit complex that regulates cullin-RING E3 ubiquitin ligases through deneddylation of cullins. Reagents targeting this subunit are commonly used by researchers studying CSN-dependent cullin modification, proteasome-mediated protein turnover, and the intersection of these pathways with cell-cycle progression and transcriptional control.

The reagent is unconjugated, allowing flexible selection of a secondary reporter or label depending on the experimental readout. Aliquoting on arrival is recommended to limit repeated freeze-thaw cycles. For research use only.
