Diagnostic pathology by EM is an area where rapid processing methods have practical applications and references can be found in Rowden and Lewis ~!. One of the earliest rapid infiltration procedures was for tissue culture cells where it took only 20 min to dehydrate. Glauert "Fixation, Dehydration and Embedding of Biological specimens.

Recent demands on laboratories to decrease specimen turnaround times for histo-logical diagnosis frequently result in the time a specimen should be allowed to fix in formalin, being curtailed. Poor or inadequate fixation leads to poor paraffin embedding which leads to the production of poor quality paraffin sections.

Glauert: Edition: reprint: Publisher: North-Holland Publishing Company, ISBN:Length: pages. Specimens are dehydrated by immersion in a graded series of alcohol or acetone, using short periods to minimize shrinkage and other tissue damage.
En bloc staining with heavy metals (to increase tissue contrast) can be done during dehydration and is recommended, especially if Spurr's resin is used.
Moreover, fixation should protect biological specimens from the denaturing effects of dehydration and all further processings. Historically, the majority of fixative solutions and fixation procedures were developed for light microscopic studies.
The choice of a fixation protocol will largely depend on the analyses to be performed. When preparing a sample (or multiple samples) for histology microscopy, there are multiple steps required. We've covered these steps in brief in a previous article on How Histology Slides are Prepared, but this article will focus on one particular procedure which needs to take place between tissue fixation and the embedding/sectioning of paraffin blocks: tissue processing.
Fixation, Dehydration and Embedding of Biological Specimens Published: 1st January Editor: A.M. Glauert. The tissue then is thoroughly dehydrated in solutions of ethanol at increasing concentrations of 50%, 70%, 95%, and %.
After dehydration, tissues are infiltrated for a prescribed time interval with an epoxy embedding medium. After infiltration, specimens are transferred into fresh epoxy resin and polymerized at 60 to 70°C for several hours.
Unfortunately, the fixation, processing, embedding, and all specimen-handling procedures, may be more suitable for one or two of these types of analyses, to the exclusion of the others (1–20). For example, it is well understood that fixative selection and fixation time affects the histological appearance of morphological details in bone.

Fixation, dehydration and embedding of biological specimens. [Audrey M Glauert]. Fixation. The specimen is placed in a liquid fixing agent A typical dehydration sequence for specimens not more than 4mm thick would be: 70% ethanol 15 min; Specimens are handled gently during embedding.
Specimens are handled forcefully during embedding to make them lie flat in the mold. Some tissue can be fractured by this process. at 4°C. Fixation at 4°C slows down autolytic processes and reduces tissue shrinkage. Nevertheless, with some specimens, fixing at 4°C can cause problems.
For example, some organelles such as microtubules can be cold labile and may be lost at low temperatures. (if you cut up the specimen in fixative, place samples in to fresh fixative). Get this from a library.

In the first three chapters, the reader is introduced to the criteria of ultrastructural preservation, artifacts and hazards. The popular chemical fixatives are described in detail, together with how they interact with biological components.Osmium vapors are extremely effective at fixing mucous membranes and should be regarded as a hazard in the lab.
All osmium fixation should be conducted in the cold for up to 2 hours -- no longer. DEHYDRATION. Dehydration is the chemical removal of water from the specimen. Common dehydrating fluids are ethanol and acetone.
