Figure 3. Scanning Electron Microscope Images of calcite modified by rhOtolin-1 alone or in combination with rmOC90.

Varying concentrations of rhOtolin-1 and rmOC90 protein, (A) 0 nM rhOtolin-1 and rmOC90; (B) 1000 nM rmOC90; (C) 667 nM rhOtolin-1; (D) 667 nM rhOtolin-1+500 nM rmOC90 were dissolved in 7.5 mM CaCl₂ growth solution. Crystals were grown for 48 hours by slow evaporation of NH₄HCO₃ into growth solution. Crystals were examined with JEOL JSM 6320F Field Emission scanning electron microscopy. Scale Bar, A, C, and D: 25 µm; B: 10 µm.
