Title: A simple photometric microassay for the quantitative evaluation of macrophage-mediated cytotoxicity on adherent cancer cells. Author: Olsson NO, Leclerc A, Jeannin JF, Martin F. Journal: Ann Immunol (Paris); 1982; 133D(3):245-54. PubMed ID: 7165278. Abstract: A new in vitro microassay was devised for the quantitation of macrophage-mediated cytotoxicity on cancer cells. After 72 h of culture with macrophages, the residual adherent target cells were stained with methylene blue. The cell-bound dye was then eluted and measured in a photometer. This assay is simple, quickly performed and gives reproducible results in good correlation with direct counting of the residual cells. It allows a quantitative evaluation of the whole toxic effect (cytostasis and cytolysis) of activated macrophages on adherent tumour cells.[Abstract] [Full Text] [Related] [New Search]
