Crystalline Ponceau MX (Ponceau R, disodium 1-(2, 4-xylylazo)-2-naphthol-3 , 6-disulphonate) labeled with 35S was synthesized from radioactive H2*SO4, β-naphthol and mxylidine, and a solution of the compound having the radioactivity of 5×105cpm/ml by gas flow counter was prepared. Then this solution was given to experimental animals to investigate the distribution and excretion of the dyestuff ...
UNLABELLED 18F-FCWAY (18F-trans-4-fluoro-N-(2-[4-(2-methoxyphenyl) piperazin-1-yl)ethyl]-N-(2-pyridyl)cyclohexanecarboxamide) is useful in clinical research with PET for measuring serotonin 1A (5-HT1A) receptor densities in brain regions of human subjects but has significant bone uptake of radioactivity due to defluorination. The uptake of radioactivity in skull compromises the accuracy of meas...
