Anti-SF2 antibodies are protein reagents that detect specific antigens. The SF2 antigen is another term for the human protein serine and arginine rich splicing factor 1, encoded by the SRSF1 gene. The protein is reported to play a role in preventing exon skipping, ensuring the accuracy of splicing and regulating alternative splicing. Canonically, it has an amino acid length of 248 residues and a mass of 27.7 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is widely expressed in many tissue types. The SF2 protein is a member of the Splicing factor SR protein family. Other alias names for SF2 include ASF and SF2p33. Indicated applications for SF2 antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry.
