Anti-PPAN Antibody

PPAN (Peter Pan Homolog) is a nucleolar protein implicated in ribosome biogenesis and the maturation of the 60S ribosomal subunit. Produced by Antibodies.com, this affinity-purified rabbit polyclonal antibody binds the human PPAN target and has been validated for Western Blot and Immunohistochemistry on human samples. The unconjugated reagent ships as 100 µl at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, supplied in a single-use vial that can be aliquoted to limit freeze-thaw cycles. Researchers investigating rRNA processing, nucleolar stress, or ribosome assembly pathways use it to probe endogenous PPAN expression in cultured cells and fixed tissue sections, and the unconjugated format allows pairing with either chromogenic or chemiluminescent detection chemistries. For long-term stability, store the vial at -20 degrees C; working aliquots may be kept refrigerated for short-term use. Reactivity has been confirmed for human, and the polyclonal nature of the reagent allows recognition of multiple epitopes on the target protein, supporting reproducible signals in both WB and IHC workflows.
