Anti-POLR3K Antibody

Rabbit polyclonal antibody targeting POLR3K, the catalytic subunit K of human RNA polymerase III responsible for transcribing small structural RNAs including tRNAs and 5S rRNA. Supplied by Antibodies.com as an unconjugated reagent in 100 µl aliquots at 1 mg/ml, formulated in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2. This primary antibody is validated for Western blot application and demonstrates reactivity with human, mouse, and rat samples, enabling cross-species investigation of Pol III complex assembly and function in comparative studies. The polyclonal nature of the reagent allows recognition of multiple epitopes on the POLR3K target, supporting reproducible detection in cell lysate and tissue extract workflows. Researchers studying transcription machinery, RNA processing pathways, and subunit composition of the Pol III complex can use this reagent to probe endogenous protein levels under varied experimental conditions. Store refrigerated at 2 to 8 degrees C and protect from light to preserve antibody activity across repeated freeze-thaw cycles and long-term experimental campaigns.
