A 1:1 mixture of protein solution and an 8:4 mixture of K2HPO4 to KH2PO4 was placed above a well of an 8:6 solution of K2HPO4 to KH2PO4. Then serially cryoprotected in situ to 40% glycerol (v/v with mother liquor) in 10% increments over a period of a few minutes. A 2.5mM solution of isocarba-DANA was then soaked into the resultant crystals for 90 minutes at a temperature of 293K. |
