Our Abpromise guarantee covers the use of ab26039 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 4 - 8 µg/ml.
IP Use at an assay dependent concentration. PubMed: 18451142
WB Use a concentration of 1.25 µg/ml. Predicted molecular weight: 109 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Efficiently joins single-strand breaks in a double-stranded polydeoxynucleotide in an ATP-dependent reaction. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination. The LIG4-XRCC4 complex is responsible for the NHEJ ligation step, and XRCC4 enhances the joining activity of LIG4. Binding of the LIG4-XRCC4 complex to DNA ends is dependent on the assembly of the DNA-dependent protein kinase complex DNA-PK to these DNA ends.
  • Tissue specificity
    Testis, thymus, prostate and heart.
  • Involvement in disease
    LIG4 syndrome
    Severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-negative/NK-cell-positive with sensitivity to ionizing radiation
  • Sequence similarities
    Belongs to the ATP-dependent DNA ligase family.
    Contains 2 BRCT domains.
