Description

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. The plasma membrane, outer alveolar membrane and inner alveolar membrane all appear as transparent tracks but the lumen of the alveolus appears electron opaque. Thickenings of the ER lying against the myoneme correspond to linkage complexes. TEM taken on 8/18/94 by D. Kunkel with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0.2µm.

Technical Details

Cells were lightly fixed with 0.25% glutaraldehyde and infiltrated with 2.3M sucrose before being frozen in liquid nitrogen and thin sectioned at a temperature of –100°C at approximately 75nm thickness. Frozen sections from these preparations were then thawed, washed, and exposed to a monoclonal primary antibody that was raised in mice or rabbit/goat and to colloidal gold-complexed goat-anti-mouse/rabbit secondary antibodies. Further details of preparation are detailed in Methods Cell Biol. 2010;96:143-73. The negative was printed to paper and the image was scanned to Photoshop. There is a high resolution version of this image in the library (CIL:39513) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
