Product Overview
This rabbit polyclonal antibody recognizes DNA-directed RNA polymerases I and III subunit RPAC2 (gene POLR1D) in human, mouse and rat samples and is validated for Western blot and ELISA.
POLR1D is a small subunit shared by RNA polymerases I and III, which together produce ribosomal RNA precursors, 5S rRNA, tRNAs and other small RNAs. It contributes to the structure of the polymerase core. POLR1D mutations are associated with Treacher Collins syndrome.

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).
