Comparison of cryofixation and aldehyde fixation for plant actin
... In chemical fixation, there is the serious danger that aldehydes may damage the antigenicity of some epitopes and hence impair their binding of antibodies. Actin is traditionally considered as one of the most sensitive structures to aldehydes (Lehrer 1981) and the early difficulties of visualizing F ...
