Effects of methylene blue stabilizer on in vitro viability and chemotaxis of (99m)Tc-exametazime-labeled leukocytes
|
This study was conducted to evaluate the effects of methylene blue/phosphate buffer stabilizer on the labeling efficiency, cell membrane integrity, chemotaxis, and in vitro stability of leukocytes labeled with ^sup 99,^Tc-exametazime. Methods: Whole blood (480 mL) was obtained from each of 3 healthy donors and divided equally into eight 60-mL aliquots. Two aliquots from each of the 3 subjects were used as a control (i.e., leukocytes were not labeled with either nonstabilized or stabilized ^su...
