Zinc(II)-cyclen polyacrylamide gel electrophoresis for detection of mutations in short Ade/Thy-rich DNA fragments.

Abstract excerpt

We describe an improved gel-based method with an additive Zn(2+)-cyclen complex (cyclen, 1,4,7,10-tetraazacyclododecane), Zn(2+)-cyclen-PAGE, for mutation detection in DNA fragments by PCR that contain more than 65% Ade/Thy bases and fewer than 100base pairs (bp). Existing techniques have a problem in analyzing such short Ade/Thy-rich fragments because the duplexes are disrupted and are not detectable due to...
