Background Information
There are at least two pathways for eukaryotes to repair DNA double-strand breaks: homologous recombination and nonhomologous end joining(NHEJ). XRCC4 is one of the core machiney of NHEJ that required for double-strand break repair and V(D)J recombination. The DNA ligase IV(LIG4)-XRCC4 complex is responsible for the NHEJ ligation step, and XRCC4 enhances the joining activity of LIG4.

Reviews
What customers say
Users report this antibody performs well for ChIP-Seq, delivering reproducible results at a 1:250 dilution in U2OS cells. For Western Blot, Immunofluorescence, and Immunoprecipitation, it works effectively for plasmid-expressed protein at 1000x dilution, though a 500x dilution is recommended for detecting endogenous XRCC4. Overall, reviewers rate the product favorably, highlighting its reliability and consistent performance across applications.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Mohammed (Verified Customer) (05-20-2026) | The product is good and gives reproducible ChIP-Seq results.
|
Mohammed (Verified Customer) (04-22-2026) | The antibody works perfect for ChIP-seq and it gives reporducible results
|
Alexandra (Verified Customer) (07-02-2024) | For plasmid expression it works fine with 1000x dilution, but for the detection of endogenous XRCC4 I recommend the use of 500x dilution.
