A thin cryosection of Vorticella exposed to a rabbit polyclonal antibody to alpha-centrin and then to gold conjugated to anti-rabbit IgG. The gold indicates that the myoneme contains alpha-centrin. Th...

The highest concentration of parasomal sacs is found in the oral region associated with the three ciliary membranelles, called in Paramecium, the ventral amd dorsal peniculi and the quadrulus. This mi...

Single computed slice through a dual axis tilt electron tomographic reconstruction of double membrane vesicles in a freeze-substituted VeroE6 cultured cell infected with the SARS-CoV. This image has ...

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 ...

Endoplasmic reticulum (ER) domains in 3D in a wild type S. cerevisiae cell (mutant = NDY257) with a 596-nm bud. Domains are color coded as follows: Golgi (purple), and vesicles (30 nm is shown in pin...

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 the b-tubulin immunogold labeled microtubules that arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this...

High resolution image of the 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-...

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...
