The contractile vacuole pore is encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell where they provide st...

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 forms a mesh around the co...

The interphase micronucleus has only a small amount of b-tubulin in its matrix or on its nuclear envelope. Segments of microtubules are scattered in the cytosol. Immunogold labeled for anti-b-tubulin....

The macronucleus contains microtubules that lie inside a seemingly intact nuclear envelope. Microtubules orient along the axis of macronuclear elongation in the form of small bundles. The section is i...

High resolution image of a monoclonal antibody raised in mouse to an antigen called C6 found on the surface of Paramecium. As seen in this micrograph the gold labelled antigen heavily labels the cilia...

We raised a monoclonal antibody in mouse to an antigen called C6 found on the surface of Paramecium. As seen in this micrograph the gold heavily labels the ciliary membrane and cell surface. In additi...
