Anti-POLR2I Antibody

Sourced from Antibodies.com, this polyclonal reagent is raised in rabbit and targets POLR2I (also known as RPB9, hRPB14.5, DNA-directed RNA polymerase II subunit RPB9, or RNA polymerase II subunit B9), the 14.5 kDa subunit that contributes to the DNA-binding groove of RNA polymerase II. The antibody is unconjugated and of the IgG isotype, supplied as a 50 µl volume at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol for routine storage. It is validated for Western blot (WB) and Immunohistochemistry (IHC) applications and has been tested on human, mouse, and rat samples, detecting endogenous levels of total POLR2I protein. The host species is rabbit and the clonality is polyclonal, making the reagent suitable for researchers investigating transcription, RNA polymerase II function, and chromatin-associated complexes across these standard model systems.
