Stabilization of marked hexametazima with technetium 99-metastables (99mTc) with chloride of cobalt hexahidratado, for the labelling of leukocytes

Presently study you work with hexametilpropilen amino oxima (HM-PAO), radiopharmaceuticals of labelling leucocytes marking it with technetium 99 recently acquired of the second elution of a generator of molybdenum technetium adding chloride of cobalt hexahidratado in different concentrations, as stabilizing agent in order to settling down if it prolongs the useful life of this expensive radiopharmaceuticals for but of minutes. For it one carries out the determination from the purity radiochemical to the 5,60,120 and 180 minutes after the labelled and the labelling of leukocytes is made with quality control of the cells after the labelling compared against a control
