Abstract: | A method for the purification of centrosomes from cultured Chinese hamster ovary cells is described. The centrosomes produced by application of this method show good retention of their intracellular morphology: the centrioles are surrounded by an “osmiophilic halo” containing numerous pericentriolar or satellite bodies. The latter spherical structures are approx. 55 nm in diameter and possess a densely staining central core surrounded by an envelope of lighter material. The number of satellite bodies associated with the centrioles seems variable, as does their spatial disposition within the osmiophilic halo. |
