Description_x000D_ Immunogen_x000D_ Recombinant protein fragment contain a sequence corresponding to a region within amino acids 252 and 426 (P26368) of U2AF65 according to AAH08740_x000D_ Application_x000D_ Suggested starting dilutions are as follows: ICC/IF: 1:100-1:1000, IHC-P: 1:100-1:1000, WB: 1:5000-1:20000. Not yet tested in other applications. Optimal working dilutions should be determined experimentally by the end user._x000D_ Physical form_x000D_ 1XPBS, 1% BSA, 20% Glycerol (pH7). 0.01% Thimerosal was added as a preservative._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ U2 auxiliary factor (U2AF), comprised of a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the U2AF large subunit which contains a sequence-specific RNA-binding region with 3 RNA recognition motifs and an Arg/Ser-rich domain necessary for splicing. The large subunit binds to the polypyrimidine tract of introns early during spliceosome assembly. Multiple transcript variants have been detected for this gene, but the full-length natures of only two have been determined to date.
