Jabbar, H. Karim, M. Al-Janabi] Sn-alanine kits were prepared in lyophilized form containing 7.02·10−2 M β-alanine and 5.5·10−4M stannous chloride dihydrate. The optimal pH value of the preparation was found to be equal to 4.3-5.1. The radiochemical purity and the stability of99mTc-alanine were assessed by gel filtration column scanning techniques (GCS) and thin layer chromatography, and the labelling yield of the complex was higher than 95%. The organ distribution data in mice showed that more than 90% of the injected dose had been accumulated in the liver. However, a negligible amount of radioactivity was detected in the non-target organs. The stability of99mTc-alanine was followed for 5 hours and the Sn-alanine kit was stable for at least 3 months.
