Product Overview
This rabbit polyclonal antibody recognizes ubiquitin-conjugating enzyme E2 K (gene UBE2K) in human, mouse, rat and monkey samples and is validated for Western blot, flow cytometry, immunoprecipitation and ELISA. The predicted molecular weight is 22.4 kDa, and the supplier reports an observed band at about 22 kDa.
UBE2K (also called HIP2 or E2-25K) is a ubiquitin-conjugating (E2) enzyme that extends Lys48-linked ubiquitin chains on proteins already carrying ubiquitin. It contributes to degradation of short-lived and misfolded proteins, including ER-associated degradation, and it was first identified as a huntingtin-interacting protein.

Reactivity Notes
The supplier lists reactivity with human, mouse, rat and monkey. UniProt places ubiquitin-conjugating enzyme E2 K in the cytoplasm. Tissue expression noted by UniProt (human): Expressed in all tissues tested, including spleen, thymus, prostate, testis, ovary, small intestine, colon, peripheral blood leukocytes, T-lymphocytes, monocytes, granulocytes and bone marrow mononuclear cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
