Anti-SRp46 (E72) Antibody

SR proteins are essential regulators of constitutive and alternative pre-mRNA splicing, and SRp46 is one such member influencing splice site selection and mRNA maturation in human cells. Antibodies.com offers this rabbit polyclonal antibody targeting SRp46, raised against the E72 epitope region, unconjugated and validated for Western blot (WB) and immunohistochemistry (IHC) workflows on human samples.

The reagent is supplied at approximately 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide as a preservative, at pH 7.2, and ships as a 100 µl vial suitable for multiple immunostaining or blotting experiments. As a polyclonal reagent from a rabbit host, it recognizes multiple epitopes on the SRp46 antigen, supporting detection in lysates and fixed tissue sections.

Researchers commonly cite the E72 antibody when probing splicing factor expression, exon inclusion patterns, or stress-responsive alternative splicing in cancer cell lines and primary tissue. Store refrigerated at 4°C; do not freeze to preserve antibody activity, and protect from light for long-term storage. For research use only.
