PDMPO-labelled silica in vitro. All [PDMPO] are 0.125 μM; All solutions are 20 mM PIPES at pH 7. All [callose] are 5% w/v. a. PDMPO only; b. PDMPO + callose; c. PDMPO + callose + 1 mM Si(OH)4; the insert shows a close-up of one of the silica clusters; d. PDMPO + callose + 2 mM Si(OH)4; the insert shows a close-up of the precipitated silica; e. PDMPO + 2 mM Si(OH)4; the insert shows a close-up of silica; f. PDMPO + callose + 4 mM Si(OH)4; the insert shows an example of silica formed in this treatment. Scale bars; 100 μm - b-f; 200 μm - a.
