Abstract
A commonly used buffer compound, tris(hydroxymethyl)aminomethane (C4H1 1NO3), was found to induce a ripple phase in supported unilamellar pho spholipid bilayers at room temperature. The ripple structure showed va rious types of domains that could extend to several micrometers in len gth with many well-defined bendings of either 120 degrees or 60 degree s. Two different periodic ripples were found to coexist in 2-dipentade canoyl-sn-glycero-3-phosphatidylcholine bilayers. Some intermediate st ates during the transition to the ripple phase were also observed.
