本文对等温自由生长和强制性溶液生长的等电溶菌酶的晶体形态进行了研究,发现这些形态变化与溶液相的流动密切相关,指出生物晶体生长停止是由于生长晶体周围的溶质贫乏造成的;通过某些手段减薄或消除这一溶质贫乏区,就可以保证晶体的持续生长。本文的研究对改善大尺寸晶体的生长提供了一条途径。
A careful study has been made on different morphologies of lysozyme crystals at isoelectric point under isothermal and constrained growth conditions. It is found that the morphologies are closely related to solution flow. Judging by the experimental results, the cessation of biological crystal growth is due to the solute-depletion zone stably existing around the growing crystals. Reducing or removing the solute-depletion zone may ensure the continuous crystal growth. This approach throws some light on the possibility of growing largedimensional biological crystals.
