Contractile Basis of Ameboid Movement
Aequorin luminescence has been utilized to determine the spatial and temporal fluctuations of the free calcium ion concentration [Ca"] in Chaos carolinensis during ameboid movement, pinocytosis, and capping. The [Ca"] increases above _10-7 M during normal ameboid movement . Three types of luminescent signals are detected in cells: continuous luminescence, spontaneous pulses, and stimulated puls...
متن کاملContractile basis of ameboid movement. VII. Aequorin luminescence during ameboid movement, endocytosis, and capping
Aequorin luminescence has been utilized to determine the spatial and temporal fluctuations of the free calcium ion concentration [Ca++] in Chaos carolinensis during ameboid movement, pinocytosis, and capping. The [Ca++] increases above approximately 10(-7) M during normal ameboid movement. Three types of luminescent signals are detected in cells: continuous luminescence, spontaneous pulses, and...

متن کاملRelations between ameboid movement and membrane-controlled electrical currents
We have studied the pattern of electrical currents through amebas (mainly Chaos chaos) with an ultrasensitive extracellular vibrating probe. Amebas drive both steady currents and current pulses through themselves. Relatively steady current with an average surface density of 0.1-0.2 muA/cm2 enters the rear quarter of an ameba and leaves its pseudopods. Streaming reversals are preceded by changes...
متن کاملLocalization of actin and myosin for the study of ameboid movement in Dictyostelium using improved immunofluorescence
The distribution of actin and myosin in Dictyostelium amebae at different developmental stages was studied by improved immunofluorescence ("agar-overlay" technique). Both were localized at the cortical region of amebae in all early developmental stages. In amebae with polarized morphology, bright fluorescence with antiactin was seen in the anterior pseudopode. The cortex in the posterior end wa...
