1	VAPOR DIFFUSION, SITTING DROP	6.5	289	BupsA.00130.a.D21 (CID4597, SMT tag on, Batch 1264062) at 10.37mg/ml (in 25mM Tris, pH8.0, 200mM NaCl, 1% glycerol, 1mM TCEP buffer) was incubated with 2mM SF355 (BSI5667). Crystals were produced by sitting drop vapor diffusion with an equal volume combination of the protein/ligand complex and a solution containing HamptonResearch PACT screen (B4): 25% PEG 1500, 100m MIB pH 7.0. The sample was cryoprotected with 15% ethylene glycol: Crystal tray ID 290655b4, puck ID PWP0-3
