Product Overview
Clone 26T03 is a rabbit monoclonal antibody that recognizes transcription initiation factor TFIID subunit 1 (gene TAF1) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 212.7 kDa, and the supplier reports an observed band at about 300 kDa.
TAF1 is the largest subunit of the general transcription factor TFIID and serves as a scaffold for assembling the complex on promoters. Beyond this structural role it carries kinase, histone acetyltransferase and bromodomain regions, and it is studied in RNA polymerase II transcription initiation, cell-cycle progression and neurological disease.

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).
