The synthesis of a new bifunctional ligand l-(4-carboxymethoxybenzyl)-N,N'-bis[(2mercapto-2,2-dimethyl)ethyl]-l,2-ethylenediamine-N,N'-diacetic acid (B6SS) is described. It consists of substitution of a side-chain, a 4-carboxymethoxybenzyl group on a carbon atom of the ethylenediamine moiety of a he
Uroporphyrins I and III have been separated by high performance liquid chromatography on a microporasil column using n-heptaneglacial acetic acid:acetone:water (90:60:30:0.05 by volume). By using uro [3H]porphyrin I and uro [l\*C]porphyrin III it was shown that less than 2% cross contamination occur
