摘要：

An in vitro microscopic fluorescence assay determining the phagocytic activity of isolated plasmatocytes of Galleria mellonella is described. It was developed to quantify insect cellular immune reactions The assay, a modification of a method originally established for vertebrate blood cells, is based on the quenching effect of trypan blue on fluorescein-isothiocyanate-labelled yeast cells. Only ingested yeast cells retain their fluorescence after quenching and can be easily distinguished from adhering ones. The technique is highly reproducible and easy to perform. Using this method a phagocytosis-stimulating effect caused by a haemolymph fraction > 100 kDa isolated from G. mellonella is demonstrated.
