Product Overview
Clone 20P61 is a rabbit monoclonal antibody that recognizes 26S proteasome non-ATPase regulatory subunit 4 (gene PSMD4) in human, mouse and rat samples and is validated for Western blot, immunoprecipitation and flow cytometry. The predicted molecular weight is 40.7 kDa, and the supplier reports an observed band at about 50 kDa.
PSMD4 (Rpn10, also called S5a) is a ubiquitin receptor of the 26S proteasome. Its ubiquitin-interacting motifs capture polyubiquitinated substrates for degradation, and it also exists outside the proteasome in a free form, making it a classic subject in ubiquitin recognition research.

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).
