Description

A high resolution view of a median longitudinal section through this collecting canal that may be artificially swollen at two sites where it is encircled by structural microtubules. Smooth spongiome forms a mesh around the collecting canal and these microtubules. Decorated tubule bundles of the decorated spongiome are sparsely scattered peripheral to the smooth spongiome. TEM taken on 7/8/96 by R. Allen with Zeiss 10A operating at 80kV. Neg. 9,780X.

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 raw film was scanned with a Nikon Coolscan 9000ED. This image is best used for quantitative analysis.
