Human recombinant erythropoietin (EPO) was successively labeled with [111In]-indium chloride after conjugation with freshly prepared cyclic DTPA-dianhydride (ccDTPA). The best results of the conjugation
were obtained by the addition of 100 i.u. of an EPO pharmaceutical solution (in phosphate buffer, pH 7.5) to a glass tube
pre-coated with DTPA-dianhydride (0.01 mg) at 25 °C with continuous mild stirring for 30 minutes. Radio thin layer chromatography
(RTLC), instant thin layer chromatography (ITLC) and high performance liquid chromatography (HPLC) showed overall radiochemical
purity of higher than 95% at optimized conditions (specific activity = 1.2–1.5 GBq/mg, labeling efficiency 80%). Preliminary
in vivo studies in normal rat model was performed to determine the biodistribution of the radiotracer up to 1 hour using scarification.
The high kidney uptake of the tracer was consistent with the reported EPO receptor distribution.

The aim of the present study was to demonstrate the possible transplacental transmission of 131I labeled recombinant human erythropoietin (131I-rh-EPO) in pregnant rats and its distribution through maternal and fetal organs. Six Wistar Albino Rats in their pregnancy
of 18 days were used 131I labeled recombinant human erythropoietin (specific activity = 2.4 μCi/IU) was injected into the tail vein of rats. After
30 minutes labeled erythropoietin infusion maternal stomach, kidney, lung, liver, brain and heart as well as fetus were removed.
Then, the same organs were removed from each fetus. Measuring weight of maternal and fetal organs as well as placenta were
followed by radioactivity count via Cd(Te) detector. 131I labeled recombinant human erythropoietin was found to be able to pass rat placenta and its distribution order in fetal organs
was similar to those of maternal organs. Besides, as measurements were performed closer to cornu uteri, uptakes were decreasing
in every fetus and its corresponding placenta.
