X-RAY DIFFRACTION ? 293 CTX-M-14 microcrystals for SFX were produced using a seeding approach. Crystals were grown by sitting drop vapor diffusion at 290 overnight mixing 1 microliter CTX-M-14 at 20 mg ml-1 and 1 microliter precipitant (40 % PEG8000, 200 mM lithium sulfate, 100 mM sodium acetate). Obtained crystals (space group P212121) were crushed and a seed stock was prepared. To obtain microcrystals the undiluted seedstock was used for batch crystallization setups by mixing volumes of 50 % CTX-M-14 with 10 % undiluted seed stock and 40 % precipitant solution.
