A high resolution view of the radial arm of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a me...

High resolution image of when the antigen was visualized with immunogold using DS-1 on thin-frozen sections the antigen could be seen to be present on the periphery of the decorated tubules. The colle...

High resolution electron micrograph of a thin frozen section treated with a clone of the mAb (D40-2) used to show the A4 antigen on decorated tubules. The immunogold lies along the outer margin of the...

Quick-freeze deep-etch view of a radial arm showing a collecting canal surrounded with smooth spongiome as well as a few decorated tubules. However several larger vesicles lie next to the radial arm c...

Occasionally mitochondria of Paramecium become filled with cristae that display a wavy or helical pattern. In thin sections these cristae are viewed as curved arcs as well as cross sectioned rows in d...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; micronucleus; contr...

Differential interference contrast image of a Paramecium (unicellular ciliate protozoa) surface. The image shows three water vacuoles contracting. Specimen observed at 100x. Judges' Special Award for...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; a segment of the ma...

When the antigen was visualized with immunogold using DS-1 on thin-frozen sections the antigen could be seen to be present on the periphery of the decorated tubules. The collecting canal and smooth sp...

A high resolution view of a median longitudinal section through this collecting canal that may be artificially swollen at two sites where it is encircled by structural microtubules. Smooth spongiome ...
