In order to quantify the effect of polyethylene glycol 4000 (PEG) on the solubility of an integral membrane protein, we have crystallized the photochemical reaction center from Rhodobacter sphaeroides Y by batch method on a large range of PEG, The measurement of the solubility diagram display a semi-logarithmic dependence of solubility versus PEG concentration, Comparison of our results with previously published ones [Odahara, T., Ataka, M. and Katsura, M. (1991) Acta Cryst. D50, 639-642] suggests a notable effect of additional 1,2,3-heptane-triol and/or temperature on photochemical reaction center solubility.
