Paraformaldehyde fixes by crosslinking surface proteins. Ethanol and methanol work through precipitation of membrane components. Triton X-100 and Tween-20 permeabilize membranes. Other permeabilizers are saponin (0.1-10% [v/v] in PBSG), L-lysophosphatidylcholine, and n-octyl-P-D-glucopyranoside (1-10 pg/mL in water). 

Methyl a-D-glucopyranoside (MGP) and octyl a-D-glucopyranoside (OGP) were oxidised to the corresponding a-D-glucuronic acids (Fig. 2.12) by RuO, [RuO ] and [RuO ] ", generated from RuClj/aq. Na(BrOj) at different pH. Of these RuO was a more effective oxidant than [RuO ]", while for [RuO ] " the oxidation was stoicheio-metric. The primary alcohol group was preferentially oxidised to the secondary alcohol functions, ascribed to the greater steric accessibility of the former cf. mech. Ch. 1 [337].
