Anti-POLR2E Antibody

Sourced from Antibodies.com, this affinity-purified polyclonal reagent is raised in rabbit against full-length recombinant human POLR2E (also known as RPB5 / DNA-directed RNA polymerase II subunit E, ~25 kDa), enabling reliable detection of endogenous POLR2E protein. The antibody is provided as a 50 µl liquid formulation at approximately 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, with a purity greater than 95% as judged by SDS-PAGE following antigen-specific affinity chromatography. It is unconjugated and is recommended for Western blot (WB) and immunohistochemistry (IHC) workflows. Cross-reactivity has been validated against human, mouse and rat samples, making it a versatile primary antibody for studies of RNA polymerase II subunit composition across species. Recommended storage is at –20 °C for long-term stability, with short-term handling at 4 °C and avoidance of repeated freeze/thaw cycles; the product is supplied with a typical lead time of 7–10 business days. As a polyclonal reagent, it offers broad epitope coverage of POLR2E, which is particularly useful when studying this shared subunit of RNA polymerases I, II and III.
