Anti-CSTF2 Antibody

Generated in rabbit and supplied as an unconjugated polyclonal preparation, this Antibodies.com primary antibody recognizes cleavage stimulation factor subunit 2 (CSTF2), the RNA-binding protein that forms part of the cleavage stimulation factor (CstF) complex and supports pre-mRNA 3′ end cleavage and polyadenylation. The 50 µl aliquot is validated for both Western blot (WB) and immunofluorescence (IF) workflows, allowing detection of CSTF2 in lysate-based or fixed-cell assays. Reactivity on human and mouse samples makes it useful for cross-species studies of mRNA maturation, transcription termination, and downstream RNA processing mechanisms. Because the product is unconjugated, it gives researchers the flexibility to pair it with a secondary detection reagent of their choice, such as HRP, Alexa Fluor, or another reporter matched to their platform. Working aliquots should be stored frozen and protected from light, with repeated freeze-thaw cycles minimized to preserve polyclonal antibody activity across multiple uses.
