摘要：

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.
