Reservoirs were 16% to 18 % 2-methyl-2,4-pentanediol (MPD) buffered with 0.1 M sodium acetate at pH 5.8 and including 0.25% octyl-beta-D-1-thioglucopyranoside. The droplets were initial composed of equal amounts of the reservoir and an 8 mg/ml solution of the protein in 0.02 M ammonium carbonate. PH範囲: 5.8 - 6.0 |
