1 | VAPOR DIFFUSION, HANGING DROP | 7.5 | 292 | A 6-fold excess of peptide 11 was dissolved in a solution of 12 mg/ml GLP1R-ECD in 10 mM Tris buffer pH 7.5, 100 mM NaSulfate and 2% glycerol. 100 nl of this protein solution plus 100 nl reservoir solution were equilibrated against reservoir solution consisting of 10 mM CoCl2, 9.4 % (v/v) 1,6-hexanediol and 100 mM NaAcetate, pH 4.8. Crystals appeared after about one week. |
