The SF1 (Ab-82) antibody is a monoclonal antibody primarily used to detect splicing factor 1 (SF1), a conserved nuclear protein involved in RNA splicing and transcriptional regulation. SF1 plays a critical role in spliceosome assembly by binding branch site sequences during early stages of pre-mRNA processing. It also interacts with other splicing factors, such as U2AF, to facilitate intron recognition. The Ab-82 clone specifically recognizes an epitope within the N-terminal region of human SF1. making it a valuable tool for studying spliceosome dynamics and RNA metabolism in molecular biology research.
Originally developed for research applications, this antibody has been widely utilized in techniques like Western blotting, immunohistochemistry, and immunofluorescence to investigate SF1 expression patterns across tissues. Studies have shown SF1's importance in cellular processes ranging from embryonic development to cancer progression, particularly in malignancies with dysregulated splicing mechanisms. Its expression is notably elevated in certain tumors, linking it to oncogenic alternative splicing events.
The antibody's validation in multiple species (human, mouse, rat) and its specificity for SF1 over related proteins enhance its utility in comparative studies. Researchers frequently employ SF1 (Ab-82) in combination with other splicing factor antibodies to dissect the spatial-temporal coordination of mRNA processing machinery. Recent applications extend to neurodegenerative disease models, where aberrant RNA splicing is implicated in pathogenesis.
