Abstract:
Trophozoites of two Acanthamoeba polyphaga strains (RYD and 435) were readily detached from plastic culture flasks or multiwell plates by 5 min exposure to a detaching fluid containing 0.005% of Triton X-100 and 0.05% ammonium sulphate. This treatment also led to rounding of cells and thus permitted convenient and reproducible counting by either hemocytometer or electronic particle counter. The detaching fluid did not impair viability even after exposure up to 1 h.
