Chemical Proteomics: Methods and Protocols (Methods in by Gerard Drewes, Marcus Bantscheff

By Gerard Drewes, Marcus Bantscheff

The multidisciplinary technology of chemical proteomics experiences how small molecules of man-made or typical foundation bind to proteins and modulate their functionality.  In Chemical Proteomics: equipment and Protocols, specialist researchers within the box supply key concepts to enquire chemical proteomics concentrating on analytical ideas, how probes are generated, ideas for the invention of small molecule goals and the probing of goal functionality, and small molecule ligand and drug discovery.  Written within the hugely profitable tools in Molecular Biology™ sequence structure, chapters contain introductions to their respective issues, lists of the required fabrics and reagents, step by step, conveniently reproducible laboratory protocols, and key pointers on troubleshooting and heading off identified pitfalls.  Authoritative and sensible, Chemical Proteomics : equipment and Protocols seeks to supply methodologies that might give a contribution to a much broader software of chemical proteomics equipment in biochemical and cellphone organic laboratories.

The strategy for immobilization has to be designed very carefully as chemical modification of any bioactive compound harbors the risk of impairing or abrogating its biological activity through disruption of the protein interaction interface.
