Etch pit formation on lysozyme crystals was observed in situ by using atomic force microscopy. The F-pit was formed at the undersaturation of 0.08〜0.14. The number of F-pits was increased with the undersaturation. DF-pits were observed to form when the undersaturation was increased over 0.30. This result suggests that the strains from the sources of the F-pits are greater than that at the DF-pits.
