Application

Anti-LIG4 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

LIG4 (ligase IV) gene encodes a DNA ligase that links single-strand breaks in a double-stranded polydeoxynucleotide. The reaction is ATP-dependent. It is involved in the ligation step during non-homologous DNA end joining (NHEJ) and V(D)J recombination. NHEJ pathway repairs double-strand DNA breaks while V(D)J recombination involves the breakage and rejoining (dependent on NHEJ) of double-strand DNA.The protein forms a complex with the X-ray repair cross complementing protein 4 (XRCC4), which improves the joining activity of LIG4. This complex interacts with DNA-dependent protein kinase complex DNA-PK. This interaction is required for NHEJ. Defects in this gene cause LIG4 syndrome, characterized by immunodeficiency and developmental and growth delay.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

In vertebrates, genomic DNA double-strand breaks (DSBs) are removed by non-homologous end-joining processes: classical non-homologous end-joining (c-NHEJ) and alternative end-joining (alt-EJ); or by homology-dependent processes: gene-conversion (GC) and single-strand annealing (SSA). Surprisingly, these repair pathways are not real alternative options

DNA double-strand breaks (DSBs) are highly cytotoxic lesions that can lead to chromosome rearrangements, genomic instability and cell death. Consequently, cells have evolved multiple mechanisms to efficiently repair DSBs to preserve genomic integrity. We have developed a DSB repair assay
