Abstract

In this first report it is described the synthesis, separation and purification of the 2-radioiodinated histamine ``125 I-labelled histamine by a mixed anhydride reaction. About 75% incorporation of I``1125, from Na``125, I, was achieved with a molecular ratio of 1:1 mixed anhydride:histamine. The radiochemical purity of the conjugate by TLC was >99% and its theoretical specific activity, 3850 mu Ci/mug. Dissolved in ethanol and held at -20 degree centigree under darkness decomposition on storage did not exceed 1% per month.
