Micrograph immunofluorescent

Although some report that antibodies are able to fully penetrate cell walls, immunofluorescence micrographs of cell-wall protein localizations suggest that this is not the case (23). Antibody solutions infiltrated under vacuum into stem...

Figure 23. Immunofluorescence micrographs in the aplanospore of 3h post-wounding of Boergesenia forbesii. Figure 23a is focused on the perinuclear microtubules, while Figure 23b is focused on the cortical microtubules which are oriented randomly.

Figure 7-32 Micrograph of a mouse embryo fibroblast was obtained using indirect immunofluorescence techniques.313 The cells were fixed with formaldehyde, dehydrated, and treated with antibodies (formed in a rabbit) to microtubule protein. The cells were then treated with fluorescent goat antibodies to rabbit /-globulins (see Chapter 31) and the photograph was taken by fluorescent light emission. Courtesy of Klaus Weber.

Although some report that antibodies are able to penetrate cell walls fully, immunofluorescence micrographs of cell-wall protein localizations suggest that this is not the case (21). Antibody solutions infiltrated under vacuum into stem tissues do not appear to reach inner surfaces of the cell walls, whereas antibodies applied to cut surfaces of the stem clearly do (see Fig. 3 in ref 21). In order to facilitate the penetration of antibodies into plant cells, the cell walls need either to be opened or removed. This is most often accomplished by digestion with the enzymes cellulase and/or pectinase (22).
