Anti-POLR2I Antibody

This rabbit polyclonal antibody from Antibodies.com recognizes POLR2I, the ninth subunit of RNA polymerase II. POLR2I is a small, approximately 14.5 kDa protein that forms part of the core Pol II enzyme responsible for synthesizing mRNA and most snRNAs in eukaryotic cells, contributing to transcription fidelity and subunit contacts within the polymerase assembly.

Supplied as 100 µl of unconjugated antiserum, the reagent is validated for western blot and immunohistochemistry workflows on human, mouse, and rat samples. The polyclonal format recognizes multiple epitopes on POLR2I, supporting detection of the denatured subunit on membranes and localization in fixed tissue sections.

Investigators studying transcription-coupled processes, RNA polymerase II subunit composition, or gene expression regulation use this Primary Antibodies reagent for detection and characterization studies. Each vial should be stored refrigerated and divided into single-use aliquots to preserve activity across freeze-thaw cycles.
