A commonly used buffer compound, tris(hydroxymethyl)aminomethane (C4H11NO3), was found to induce a ripple phase in supported unilamellar phospholipid bilayers at room temperature. The ripple structure showed various types of domains that could extend to several micrometers in length with many well-defined bendings of either 120 degrees or 60 degrees. Two different periodic ripples were found to coexist in 1,2-dipentadecanoyl-sn-glycero-3-phosphatidylcholine bilayers. Some intermediate states during the transition to the ripple phase were also observed.
一种常用的缓冲化合物，三（羟甲基）氨基甲烷（C4H11NO3），被发现在室温下能在支撑的单层磷脂双分子层中诱导出波纹相。波纹结构显示出各种类型的畴，其长度可延伸至几微米，有许多明确的120度或60度弯曲。在1,2-二五烷酰基-sn-甘油-3-磷脂酰胆碱双分子层中发现两种不同的周期性波纹共存。还观察到了向波纹相转变过程中的一些中间状态。
