Anti-SFRS1 Antibody

SFRS1 (also known as SRSF1 or ASF/SF2) is a prototypical member of the SR family of splicing factors, and this rabbit polyclonal primary antibody from Antibodies.com provides a reliable tool for its detection. SFRS1 functions in constitutive and alternative pre-mRNA splicing, regulates mRNA export and translation, and contributes to genome maintenance, making it a frequent target of investigation in RNA processing, cancer biology, and developmental studies.

Validated for Western blot (WB), Immunohistochemistry (IHC), and Immunofluorescence (IF), the antibody cross-reacts with Human, Mouse, and Rat samples, supporting use across a broad spectrum of model systems. It is supplied as an unconjugated, polyclonal preparation at 1 mg/ml in Phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2.

The 100 µl vial is intended for research use only and should be stored refrigerated to preserve activity; aliquot upon first use if extended storage is anticipated. Researchers commonly apply this reagent to study SR protein phosphorylation, exon inclusion/skipping decisions, and the role of SFRS1 in oncogenic transformation, where overexpression has been linked to several tumor types.
