FIG. 2. Protein composition of sugradient fractions obtained from solubilized C. reinhardtii thylakoids. a, SDS-PAGE of sucrose gradient fractions. b, Western detection of PSI core and LHCI subunits. M, prestained protein markers with their apparent molecular mass (in kDa) indicated on the left; T, thylakoids; .T, DDM-solubilized thylakoids following partial PSII depletion; F1- see Fig. 1 legend. Proteins were loaded at 5 and 2 .g Chl in a and b, respectively.
