Anti-SFRS9 Antibody

SFRS9 (also known as SRSF9 or SRp30c) is a member of the arginine-serine rich (SR) family of pre-mRNA splicing factors, and this polyclonal reagent from Antibodies.com targets that protein for detection by Western blot. The antibody is raised in rabbit, is of the IgG isotype, and is supplied unconjugated at 50 µl per vial, giving enough material for multiple blots depending on working dilution. It has been validated for reactivity with both human and mouse samples, making it useful across common model systems and human cell-line work where SRSF9 expression, isoform usage, or phosphorylation status is being investigated. Because SRSF9 contributes to alternative splice-site selection as well as to mRNA export and stability, researchers apply this reagent to follow changes in expression during differentiation, stress responses, oncogenic transformation, and splicing-factor reprogramming studies. The unconjugated format lets the end user pair it with a secondary antibody of choice and adopt chemiluminescent, fluorescent, or near-infrared detection chemistries as the experiment requires, and the polyclonal background provides broader epitope coverage than a monoclonal reagent when mapping modified or isoform-distinct forms of SRSF9.
