| 1 | VAPOR DIFFUSION, HANGING DROP | 7.4 | 293 | A 20 uL pellet of 50 mM cadmium sulfate in 2% agar was deposited on a cover slip. Adjacent to this was positioned ferritin (10 ul of 50 mg/ml ferritin, Sigma F4503) and precipitant (10 ul of 3.5M Ammonium Sulfate and 100 mM Tris pH 7.4). The cover slip was equilibrated over 3.5 M Ammonium Sulfate |
