the uptake by normal organs , especially the liver , was greater for ma-dtpa , ca-dtpa , and scn-bz-edta chelate-b72.3 igg ( 1.3:1 to 2.5:1 ) in comparison to that found with the b72.3-scn-bz-dtpa ( approximately 5:1 ) and abdominal organ , and uptake was very prominent on imaging with these chelate-mab complexes but was virtually absent in the mice injected with b72.3-scn-bz-dtpa .
