Binding profiles of PfN44. PfN44 was labeled with rhodamine and then incubated with calcite or aragonite. The rhodamine labeled BSA was used as a control. Scale bar, 20 μm. 109 crystals were examined, and 105 crystals showed the same pattern in the calcite binding assay. 124 crystals were examined, and 114 crystals showed the same pattern as shown in the aragonite binding assay.
