DNA polymerase eta is specifically involved in DNA repair. It plays an important role in translesion synthesis, where the normal high fidelity DNA polymerases cannot proceed and DNA synthesis stalls. It also plays an important role in the repair of UV-induced pyrimidine dimers. Depending on the context, it inserts the correct base, but causes frequent base transitions and transversions. It targets POLI to replication foci.
Applications:
Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.
Recommended Dilution:
Western Blot: 1:2000-1:10,000
Immunoprecipitation: 2-5ug/mg lysate
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
