The micronuclear separation spindle. Nuclear pores are not empty perforations but are closed by nonetchable material. The separation spindle must elongate as microtubules lengthen and/or slide against...

A view of the ER on which IMPs are organized into lines, arcs, and circles indicating organization of proteins within the ER membrane and possibly peripheral proteins attached to its cytosolic surface...

Tangential fractures through mature trichocysts. The planes in the paracrystalline stacks are exposed. The body is laced to the membrane but such associations must be severed when the trichocyst is di...

DVD quality video of the Contractile Vacuole Complex of Paramecium multimicronucleatum. In vitro CVC rounding/relaxing cycles. An in vitro CV in a ruptured Paramecium cell is surrounded by cytoplasmic...

Rabbit psoas skeletal muscle fibers were held at constant length and rigor induced by immersion in 0.2% saponin. The fibers were quick-frozen by contact with a liquid helium-cooled copper block in a ...
