Freeze-substitution of gram-negative eubacteria: general cell morphology and envelope profiles.

Graham, L L, Harris, R, Villiger, W, Beveridge, T J

Freeze-substitution was performed on strains of Escherichia coli, Pasteurella multocida, Campylobacter fetus, Vibrio cholerae, Pseudomonas aeruginosa, Pseudomonas putida, Aeromonas salmonicida,...

Coralline shape of the bacterial nucleoid after cryofixation.

Bohrmann, B, Villiger, W, Johansen, R, Kellenberger, E

A new procedure of immunostaining sections of cryofixed and freeze-substituted Escherichia coli shows that DNA extends from its bulk into small ribosome-free spaces throughout the cytoplasm,...

Periplasmic gel: new concept resulting from the reinvestigation of bacterial cell envelope ultrastructure by new methods.

Hobot, J A, Carlemalm, E, Villiger, W, Kellenberger, E

Bacterial cell envelope ultrastructure was investigated both by the progressive lowering of temperature embedding technique and freeze-substitution, using conventional and scanning transmission...

Shape and fine structure of nucleoids observed on sections of ultrarapidly frozen and cryosubstituted bacteria.

Hobot, J A, Villiger, W, Escaig, J, Maeder, M, Ryter, A, Kellenberger, E

Very rapidly frozen cells of Escherichia coli and Bacillus subtilis were substituted at low temperature into acetone with 1% OsO4 and embedded in Epon. They showed ribosome-free spaces filled with...

Assembly of subcomponents C1r and C1s of first component of complement: electron microscopic and ultracentrifugal studies.

Tschopp, J, Villiger, W, Fuchs, H, Kilchherr, E, Engel, J

Monomeric C1s (Mr, 85,000; s20,w, 4.3S), a subcomponent of first component of complement (C1), the dimer (Mr, 170,000; s20,w, 6.7 S) of C1r, another subcomponent, and the tetrameric complex...

A SCANNING AND TRANSMISSION ELECTRON MICROSCOPE STUDY OF ANTIGEN-BINDING SITES ON ROSETTE-FORMING CELLS

Gudat, Fred G., Villiger, W.

The ultrastructure of binding sites in rosette-forming cells of mice after immunization with sheep red cells was studied by means of scanning and transmission electron microscopy. It was found that...
