The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 4 - 8 µg/ml.
Use at an assay dependent concentration. PubMed: 18451142
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.
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.
Testis, thymus, prostate and heart.
