When the thylakoid membranes of brown alga Undaria pinnatifida were solubilized by DMG and subjected to PAGE intwo electrophoresis systems, there were eight kinds of pigment-protein complexes separated in Tris-Gly system, and they were CPⅠ a、CPⅠ、LHC1、CPa、LHC2、LHC3、LHC4、LHC5. In Tris-Boric acid system, five kinds of pigment-protein complexes wereisolated, and they were CPⅠ、CPa、LHC1、LHC2、LHC3. The absorption and fluorescence emission spectra were measured andcompared. The results show that the characteristics of the sane kind of pigment-protein complexes resolved from differentelectrophoresis systems are similar.
