Anti-SFRS1 Antibody

Targeting the serine/arginine-rich splicing factor SFRS1 (also known as SRSF1), this rabbit polyclonal primary antibody from Antibodies.com is supplied at a 100 µl volume as an unconjugated reagent validated for Western blot (WB), immunohistochemistry (IHC), and immunofluorescence (IF) applications. SFRS1 is a member of the SR protein family and acts at the core of constitutive and alternative pre-mRNA splicing, with additional roles in mRNA nuclear export, translation, and nonsense-mediated decay. Raised in rabbit, the reagent is reactive with human, mouse, and rat samples, supporting comparative studies across cell lines and tissue types. Researchers frequently use it to profile SFRS1 expression in tumor versus normal specimens, dissect splicing-factor dependencies in cancer pathways, and localize SR proteins to sub-nuclear speckle domains by imaging. For best performance, store the antibody frozen in small aliquots, protect from light, and minimize freeze-thaw cycles so that polyclonal binding activity is preserved across repeated experiments. Each vial is supplied ready for standard immunoblotting and chromogenic or fluorescent staining protocols.
