    pH 7.4
    Details PROTEIN AT 10MG/ML IN 15MM NACL, 10MM HEPES, PH7.4, MIXED WITH WELL BUFFER (50MM AMMONIUM ACETATE, 10% PEG4K, 0.1M HEPES PH 7.4) IN EQUAL VOLUMES, THEN VAPOUR DIFFUSION AGAINST WELL BUFFER. CDK2 CRYSTALS WERE SOAKED FOR 20 HOURS IN A SOLUTION OF 0.5MM NU2058 IN 1X WELL BUFFER PREPARED FROM STOCKS 2X WELLBUFFER AND 10MM NU2058 IN 100% DMSO.
