I have used the polyester wax (Steedman's wax) a lot for immunofluorescence
in plants (with antibodies for actin, tubulin, FtsZ, GFP, c-myc, and
other). I remember there were some old papers where the wax was used for
decalcified bones. Unfortunately these reprints were left behind during my
last move, but a quick search found a couple papers that may be relevant:

1-Hexadecanol - Superior Embedding Wax for Warm Climates. Stain Technology,
1972. 47(6): p. 313-&.
2. Goodwin, J.R., Polyester Wax Processing of Tissues - Some New
Techniques and Detailed Procedures. American Journal of Medical Technology,

7. Richardson, L.L. and Dym, M., Improved Adhesiveness of Polyester
Wax Sections for Immunocytochemistry. Biotechniques, 1994. 17(5): p. 846-848.
As far as handling and sectioning, I was quite happy with the sectioning
properties; I was cutting sections between 5 and 15 microns.
There are few tricks that are useful to make the sectioning work well; see
the book chapter:
Vitha, S., Baluka, F., Jasik, J., Volkmann, D., and Barlow, P., Steedman's
wax for F-actin visualization, in Actin: a Dynamic Framework for Multiple
Plant Cell Functions, C.J. Staiger, F. Baluka, D. Volkmann, and P. Barlow,
Editors. 2000, Kluwer: Dordrecht, The Netherlands. p. 619-636.
You can download the PDF from
The disadvantage of the above method is that the ribbons sometimes do not
100%, or al least not all sections; for what I was doing it was not
critical, I was more interested in cellular and subcellular immunostaining
rather that looking at tissue and whole-organ morphology.
