BACKGROUND To improve efficiency in high throughput protein structure determination, we have developed a database software package, Gene Composer, which facilitates the information-rich design of protein constructs and their codon engineered synthetic gene sequences. With its modular workflow design and numerous graphical user interfaces, Gene Composer(More)
We describe buffer for both immunoelectrophoresis and zone electrophoresis procedures in agarose gels, Tricine [N-tris(hydroxymethyl)methylglycine] and Tris [2-amino-2-(hydroxymethyl)-1,3-propanediol] being the main components. This buffer eliminates the procurement cost and inventory control associated with formulation of barbital buffers. We compare it(More)
Crystallization of a maltose-binding protein MCL1 fusion has yielded a robust crystallography platform that generated the first apo MCL1 crystal structure, as well as five ligand-bound structures. The ability to obtain fragment-bound structures advances structure-based drug design efforts that, despite considerable effort, had previously been intractable by(More)
OBJECTIVE Much of what we know about ethical issues in palliative care comes from the perceptions of physicians and ethicists. In this study our goal was to hear other voices and to gain first-hand knowledge of the possibly contrasting views of patients, their families, nurses, volunteers, and other team members on end-of-life issues. DESIGN Qualitative(More)
BACKGROUND With the goal of improving yield and success rates of heterologous protein production for structural studies we have developed the database and algorithm software package Gene Composer. This freely available electronic tool facilitates the information-rich design of protein constructs and their engineered synthetic gene sequences, as detailed in(More)
When starting a protein-crystallization project, scientists are faced with several unknowns. Amongst them are these questions: (i) is the purity of the starting material sufficient? and (ii) which type of crystallization experiment is the most promising to conduct? The difficulty in purifying active membrane-protein samples for crystallization trials and(More)

The crystallization of membrane proteins in amphiphile-rich materials such as lipidic cubic phases is an established methodology in many structural biology laboratories. The standard procedure employed with this methodology requires the generation of a highly viscous lipidic material by mixing lipid, for instance monoolein, with a solution of the detergent(More)
