NE-CAT maintains a chemistry laboratory for use by its resident staff members and beam line users adjacent to the Sector 24-ID beamlines. The laboratory is equipped for protein crystallization and crystal soaking experiments. Chemicals normally used are readily available as well as routine chemical equipment such as analytical balances, a pH meter, an ultrasound dismembrator, a table-top refrigerated shaker, a high-speed refrigerated Eppendorf centrifuge, a UV/Vis spectrophotometer, and two high-power stereo zoom microscopes. In addition, there is a Agilent 2100 Bioanalyzer available for fast and precise characterization of molecular weights and concentrations of proteins and DNA, and a dynamic light scattering apparatus which can be used to provide unique insights into the behavior of biomolecules in solution by measuring the hydrodynamic radius and polydisersity of macromolecules. One temperature controlled incubator is available at 18 ºC.
