1VAPOR DIFFUSION, SITTING DROP7.4298ASPERGILLUS FUMIGATUS VCID8013 [CALCINEURIN A], VCID8015 [CALCINEURIN B] AND VCID10288 [FKBP12] IN A SEC PURIFIED COMPLEX MEDIATED BY FK506/ TACROLIMUS AT 9.8 MG/ML [PROTEIN BATCH # 1393038]. PROTEIN BUFFER INCLUDES 25MM HEPES PH 8.0, 50 MM NACL, 5.0MM CACL2, AND 0.5MM TCEP. THE PROTEIN COMPLEX WAS CRYSTALLIZED AGAINST AN OPTIMIZATION SCREEN BASED ON THE SPARSE MATRIX SCREEN PACT CONDITION E9: 0.1M HEPES/NAOH, PH7.4, 0.2M POTASSIUM/SODIUM TARTRATE, 22.27% W/V PEG 3,350 AND CRYO-PROTECTED WITH 20% ETHYLENE GLYCOL
