Sum peak method applied to the study of human platelet cells.
The sum peak method based on the phenomenon of perturbed angular correlation was applied to study the chemical environments of 111In in intact platelet cells. The sum peak appearing in the gamma-ray spectrum of 111In which emits two gamma-rays in cascade was observed for 111InCl3 solutions and 111In-labeled platelets. An increase in intensity ratios of the sum peak to its single peak was found when 111In incorporated into platelets from its aqueous solution. This fact was discussed in terms of physico-chemical environments of 111In together with an evaluation of sum peak analysis in the spectra.
