Anti-PWP2 Antibody

This polyclonal reagent from Antibodies.com targets PWP2 (Periodic Tryptophan Protein 2), a WD-repeat protein that functions within the 90S pre-ribosome and SSU processome during early ribosome biogenesis. Raised in rabbit, the antibody is supplied as an IgG preparation at a 50 µl volume, unconjugated and ready for western blot workflows. Reactivity has been confirmed against human and mouse samples, supporting comparative studies of rRNA processing and nucleolar function across these two species. Recommended applications include western blot analysis of whole-cell lysates to follow pre-ribosomal assembly dynamics, monitor U3 snoRNA pathway engagement, or probe perturbations in 40S subunit maturation. For best stability, store refrigerated between uses, protect from light, and aliquot working stocks to limit repeated freeze-thaw cycles.
