Macrophage adherence inhibition assay: measurements of adherent cells by the TV image analysis system Densitron

A procedure is described to automate the cell counting step in the indirect macrophage adherence inhibition assay using the TV image analysis system Densitron. Comparison of the results of direct visual counting and of Densitron measurements of the adherent cells in the haemocytometer chamber indicates the qualification on principle of Densitron to substitute the time consuming and exerting visual counting procedure.
