1	VAPOR DIFFUSION, SITTING DROP	3	289	APO FCRN CRYSTALS WERE PRODUCED BY SITTING DROP VAPOR DIFFUSION WITH AN EQUAL VOLUME COMBINATION OF THE PROTEIN COMPLEX, PROVIDED IN A PROTEIN SOLUTION CONTAINING 50MM HEPES PH 7.0 AND 75MM NACL, AND AN OPTIMIZATION SCREEN CONTAINING 0.1M CITRIC ACID/NAOH PH 3.01-3.09 AND 12-16% W/V PEG 6,000. CRYSTALS OF FCRN WERE SOAKED FOR THREE DAYS IN BUFFER CONTAINING 0.1M CITRIC ACID/NAOH PH 3.0, 20% W/V PEG6,000, AND 20% GLYCEROL AND 12.5MM UCB-303.
