Sigma-Aldrich: Mar 8, 2005


Sigma-Aldrich has launched a new online assay library on its web-based Enzyme Explorer, the company said last week.

The assay library contains over 600 detailed procedures for measuring enzyme activity and related metabolites, Sigma-Aldrich said, and is the result of over ten years of in-house process development by Sigma-Aldrich scientists.

The Enzyme Explorer features in-depth resources on protein research, including new metabolic pathway animations, Sigma said. The addition of the assay library enhances the technical content, which is available free to all researchers, the company said.
