Product Overview
Clone 28C83 is a rabbit monoclonal antibody that recognizes COP9 signalosome complex subunit 8 (gene COPS8) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 23.2 kDa, and the supplier reports an observed band at about 20 kDa.
COPS8 (CSN8) is the smallest subunit of the COP9 signalosome, the complex that deneddylates cullins and thereby regulates cullin-RING ubiquitin ligases. It contributes to complex assembly and function, and COPS8 is studied in ubiquitin-dependent protein turnover and development.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
