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...

High resolution micrograph that shows the pegs on the surface of the decorated tubules that are negatively stained by the uranyl acetate dissolved in the methylcellulose solution used to give support ...

The membrane along the collecting canal of ruptured cells shows that the excess smooth spongiome membrane forms a three-dimensional array similar to etiolated chloroplasts when a piece of wood stays o...

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...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

A high resolution micrograph of the Contractile Vacuole Complex membrane system to determine what happens to the CV during systole we observed the CV in a living cell and then fixed the cell as soon a...

High resolution image of the decorated spongiome is composed of 50nm tubules that have a pattern of helically wound subunits attached to their cytosolic surfaces. These tubules can be up to one microm...

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...

The contractile vacuole of V. convallaria empties into a convoluted chamber. This chamber is covered by the alveoli and plasma membrane of the pellicle and is open to the cell’s surface via the peri...

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 ...
