Product Overview
Clone 21E35 is a rabbit monoclonal antibody that recognizes transcription factor COE1 (gene EBF1) in human and mouse samples and is validated for Western blot. The predicted molecular weight is 64.5 kDa, and the supplier reports an observed band at about 64 kDa.
Early B-cell factor 1 (EBF1) is a pioneer transcription factor that commits lymphoid progenitors to the B-cell lineage. Working with factors such as E2A and PAX5, it opens chromatin, activates B-cell genes and represses alternative fates, so it is central to studies of B-cell development and leukemia.

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).
