1	VAPOR DIFFUSION, HANGING DROP	8	296	For crystallization, InvA (356-525) was concentrated to 25mg/ml in a buffer containing 25mM Tris pH 8.0, 200mM NaCl, 2mM DTT. Crystals were grown by vapor diffusion using hanging drops formed from mixing a 1:1 volume ratio of InvA (356-525) protein with an equilibration buffer consisting of 1.6M Ammonium sulfate, 0.1M MES pH 7.0, 8% Dioxane at 230C. , VAPOR DIFFUSION, HANGING DROP, temperature 296K
