... slightly the amount of the MREa–Ku proteincomplex (Fig. 2B, lane 7), possibly due to the ability of the Ku protein to bind DNA in a sequence-independent manner[48,49]. In the MREa–protein complex ... EMSAs.N-terminal sequencing of the 70-kDa protein was inhibitedby modification, consistent with previous reports showingthat the amino terminus of the human Ku-70 protein isblocked and therefore inaccessible ... IR. Results of each values were expressed as the following ratio: intensity of WD cDNA/intensity of competitor and then divided by intensity of amplified actin cDNA. PC, the result of competitive...
