Ku (p70/p80)

Eukaryotic Ku is a heterodimeric DNA binding protein formed by the p70 and p80 subunits that were named according to their respective molecular weight. Ku is a key factor of the non-homologous end joining (NHEJ) DNA repair pathway by directly binding to DNA ends created at DNA double strand breaks. DIARECT™ antigens are for further manufacturing or research use only.

Recombinant. Expressed by recombinant baculovirus (Autographa californica multiple nuclear polyhedrosis virus; AcMNPV) infection of Spodoptera frugiperda Sf9 insect cells.
