Anti-U2AF1L4 Antibody

This rabbit polyclonal antibody from Antibodies.com targets U2AF1L4 (U2 small nuclear RNA auxiliary factor 1-like 4), a splicing auxiliary factor implicated in 3' splice site recognition during pre-mRNA processing. Raised in rabbit and purified as an IgG preparation, the reagent is supplied unconjugated at 50 µl per vial and is validated for Western blot (WB) and immunofluorescence (IF) workflows on human samples.

U2AF1L4 functions as a paralog of the canonical splicing factor U2AF1 and contributes to exon definition through interaction with the AG dinucleotide at the 3' end of introns. Research groups studying RNA biology, spliceosome assembly, and post-transcriptional gene regulation use this reagent to probe U2AF1L4 expression across human cell lines and primary tissues, including investigations into differential isoform usage in development and disease contexts.

For handling, the antibody should be stored at -20 °C in working aliquots to limit freeze-thaw cycles, with brief centrifugation before opening the vial. It is intended for research use only and is not approved for diagnostic or therapeutic applications.
