Abstract
Improvements in calorimetric assays, surfaces for arraying microcolonies and instrument hardware for screening mutagenized enzymes and proteins in a solid phase format are presented. These improvements permit new enzyme activities to be screened. New filter membrane materials and formats for arraying the microcolonies provide higher throughput, better solvent resistance and ease of handling. Modifications to the instrument heating and illumination systems provide improved temperature control and a more compact, folded light path.
