1. However, more enduring chemical bonds are formed when C60 reacts with osmium and platinum.
2. Biopsy specimens were fixed in 2.5% phosphate buffered glutaraldehyde, and then fixed for one hour in 2% osmium tetroxide in the same buffer.
3. Biopsy specimens from the remaining seven subjects were divided for routine microscopy (fixation in buffered formalin), for silver staining (fixation in formol saline) and for histochemistry (snap frozen in hexane at -80C); a portion was taken for electron microscopy (fixation in 2.5% glutaraldehyde in 0.1 M cacodylate buffer containing 2.5 mM CaCl 2 at pH 7.4, postfixation in 1% osmium tetroxide and processed into araldite by conventional methods).
4. To preserve actin filaments (at the expense of good membrane preservation), we used a protocol from K. McDonald: limb buds were fixed in cacodylate-buffered 1% glutaraldehyde, rinsed in buffer, treated with 0.8% K 3 Fe(CN) 6 in buffer for 30min, postfixed with 0.5% osmium tetroxide in buffer for 1min, embedded in Araldite, sectioned and stained with uranyl acetate and lead citrate.
5. Osmium tetroxide forms 1:1 and 2:1 adducts and, by using carbon 13 NMR it has proved possible to discern C60's two types of C-C bonds (J. M. Hawkins et al, J. Am.
6. pure platinum, palladium, rhodium, ruthenium, iridium and osmium metal
7. RPM operates three mines whose primary product is platinum, in addition to palladium, rhodium, iridium, ruthenium, osmium, gold, silver, copper, and nickel.
8. (ii) Post-fix in 1 % OsO4 (osmium tetroxide) in 0.1 M sodium cacodylate (pH 7.3) for 30 min at room temperature.
9. Specimens were fixed in half-strength Karnovsky fixative, postfixed in osmium tetroxide, embedded in Araldite, thin sectioned and stained with uranyl acetate and lead citrate in the usual way.
10. The cells were fixed in 48% glutaraldehyde for 24 hours, then fixed in osmium tetroxide, and stained with uranyl acetate on nickel grids using standard techniques.
11. For electron microscopy, the cells were fixed in 2% glutaraldehyde in PB for 45min at 37C, post-fixed in 1% osmium tetroxide for 30min at 4C, stained in uranyl acetate, dehydrated through graded ethanol and embedded in Epon 812 resin.
12. Specimens were fixed in half-strength Karnovsky fixative (2% formaldehyde plus 2.5% glutaraldehyde in 0.075M cacodylate buffer, pH 7.4) at 0, 1, 3, 6, 12, 18 and 24h after wounding, postfixed in osmium tetroxide, and prepared for scanning electron microscopy in the standard way.
