Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000
Simple Western™ 1:10 - 1:50

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

SRSF7 (F9G2P) Rabbit mAb recognizes endogenous levels of total SRSF7 protein. Based on the sequence of the peptide antigen, this antibody is expected to detect isoforms 1-4 of SRSF7.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro86 of human SRSF7 protein.

Background

The serine/arginine-rich family of splicing factors are crucial regulators in precursor RNA splicing, a process that is associated with maintenance of genome stability, regulation of mRNA export and stability, and translation (1).

Serine/arginine-rich splicing factor 7 (SRSF7/SFRS7), also known as splicing factor 9G8, is overexpressed in colon and lung cancer, and regulates proliferation and apoptosis through the splicing of Fas mRNA in human colon and lung cancer cells (2). In human colon cancer cells, SRSF7 knockdown increased levels of the CDK inhibitor p21 Waf1/Cip1 in a p53-independent manner (3). SRSF7 also regulates age-dependent splicing in mice (4) and induces expression of cellular senescence markers in response to DNA damage by generating an alternatively spliced form of p53, p53β (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
