Abstract

Diethylene triaminopentaacetic acid (99mTc-DTPA) is one of the technetium radiopharmaceuticals mostly used in renal imaging for evaluation of glomera filtration rate. The 99mTc-DTPA binding rates on plasma proteins was investigated using two useful and reproducible methods. Equilibrium Dialysis (ED) and Ultrafiltration (UF) are described and there are performances compared. 99mTc-DTPA binds strongly to Human Serum (HS) than to Human Serum Albumin (HSA). In our assay, using UF technique, we found the binding rates were in HS 48.72 % ±2.58 and 51 % ±1.43 for respectively two 99mTc-DTPA concentrations [1mg/L] and [2mg/L]. Using ED method we found the binding rates were in HS 11.22 % ±2.17 and 14.94 % ±2.30 for respectively two 99m Tc-DTPA concentrations [1mg/L] and [2mg/L]. Moreover, According to HSA concentrations, the 99m Tc-DTPA binding rates increase using both techniques.
