A New Radioisotopic Microassay of Cell-Mediated Immunity Utilizing Technetium-99m Labeled Target Cells

Academic Article


  • The Tc microcytotoxicity assay is a simple and sensitive means of assessing cell-mediated immunity in vitro. The short labeling time and high binding affinity of the nuclide are significant advantages over other radioisotopic assays which have been described. The short half-life is adequately compensated for by the high labeling efficiency and specific activity of the isotope. We thank Ms. K. Gollahon and L. Wickens for expert technical assistance and Ms. K. Phipps and L. Conaughton for secretarial assistance. © 1973, SAGE Publications. All rights reserved. 99m
