Notes

A quantitative bioassay for ciliate chemotaxis based on the capillary principle is described using Tetrahymena thermophila as test organism. The attractant-containing assay tube designed for the bioassay attracts up to 4x10(4) cells in 2 hr which makes electronic cell counting of the chemotactic response feasible. The attractants used are solutions of proteose peptone and yeast extract which also are growth media for this organism.
