Anti-CSTF2 Antibody

Generated in rabbit, this polyclonal reagent targets CSTF2 (cleavage stimulation factor subunit 2), an RNA-processing factor that contributes to 3'-end cleavage and polyadenylation of pre-mRNAs. The unconjugated antibody is supplied at 100 µl and is validated for Western blot and immunofluorescence workflows, with confirmed reactivity against human and mouse samples. Investigators studying transcription termination, alternative polyadenylation, and broader mRNA 3'-end processing can use this Antibodies.com reagent to detect endogenous CSTF2 in whole-cell lysates and in fixed-cell preparations. Because the reagent is polyclonal, it binds multiple epitopes across the target protein, which can be advantageous when probing truncated isoforms or post-translationally modified forms of CSTF2. The unconjugated format gives users flexibility to pair the antibody with their own secondary detection reagents, whether HRP-based for chemiluminescent Western blot or fluorophore-conjugated antibodies for immunofluorescence imaging.
