Crystal structure of FcRn bound to UCB-84
Crystallization Crystalization Experiments ID Method pH Temperature Details 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
3.0 AND 20% 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 PEG 6,000, AND 20% GLYCEROL AND 20MM UCB-84).
