Immunohistochemistry (IHC)

(Formalin-fixed and paraffin-embedded human hepatocarcinoma tissue reacted with U2AF1 antibody (Center S70), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.)

Western Blot (WB)

(Western blot analysis of anti-U2AF1 Antibody (Center S70) in Ramos cell line lysates (35ug/lane).U2AF1(arrow) was detected using the purified Pab.)

Western Blot (WB)

(Western blot analysis of U2AF1 (arrow) using rabbit polyclonal U2AF1 Antibody (Center S70). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected (Lane 2) with the U2AF1 gene.)

Uniprot Description

U2AF1: Plays a critical role in both constitutive and enhancer- dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3'-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron. Belongs to the splicing factor SR family. 4 isoforms of the human protein are produced by alternative splicing.
