Abstract:
A system and method for sensitive measurements of molecular binding as a function of time and temperature provided by a surface plasmon resonance (SPR) instrument producing a stable temperature gradient over the sensor surface. Continuous monitoring of reflected light intensity from different locations of the sensor allows simultaneous measurement of time and temperature dependence of binding interactions.

Abstract:
A method of expressing proteins is disclosed. In a preferable embodiment, the method comprises placing a DNA sequence encoding a protein or peptide and expression vector containing a regulatable promoter expressible in Rhodospirillum rubrum and expressing the protein within a bacterial host, wherein the host has extra capacity for membrane formation and wherein the host is a member of the genus Rhodospirillum.
Abstract:
A composition and method for forming investment casting shells includes using colloidal silica, zircon flour, and fused silica in a slurry which is applied to a pattern. After the slurry is applied to the pattern, it is allowed to partially or completely solidify. After the shell has solidified, the pattern may be melted or otherwise removed. A molten material is introduced into the shell and allowed to cool to form an article. Finally, the shell is broken away or otherwise removed from the article. The improved shell slurry composition and corresponding method minimizes pattern-to-pour cycle times and is environmentally friendly.
