Surface pattern of P. tetraurelia in a region with two basal bodies in each cortical unit. This is a thin-frozen section labeled with immunogold showing the location of b-tubulin. The gold lies over t...

The dividing macronucleus may be porous to microtubules. Segments of microtubules are found both outside and inside the nuclear envelope in this figure although one cannot follow a single microtubule ...

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...
