In this sense , ida plays dual effects , tridentate chelating to cu ( 2 ) and bridge between two cu ( 1 ) andcu ( 2 ) . 3 metal complexes were selected as the appropriate for the study of cleavage plasmid pbr322dna by gel electrophoresis technique . the results showed ni and mn complexes could cleave effect - ively dna in the presence of h2o2 at physiological ph and temperature , whereas individual zn complex could cleave effectively dna 通过电泳实验研究了一系列金属配合物与pbr322dna的作用,发现在tris - hcl缓冲溶液中,生理条件下,镍、锰配合物在共反应物h _ 2o _ 2存在下能够很好的断裂dna ,而zn配合物单独作用就能够使dna由ccc型转化为oc和linear型。
