Center for Molecular Medicine
Dedicated to understanding the intricacies of cellular signaling, the Center for Molecular Medicine was built on Caltech's successes at the interface of chemistry and biology. It is focused on determining how complex systems of molecules interact to create the pathways that regulate the lives of cells and allow them to respond to their environments. Rather than just studying a complex biomolecule in isolation, an understanding of how it is part of a larger path of molecules is the purpose of its establishment. The Center was made possible by a generous grant from the Gordon and Betty Moore Foundation.
If use of the Center instrumentation has contributed significantly to your research, we request that you cite the Center in the acknowledgments section of your publication. For example: "This work was supported by…, and by the Center for Molecular Medicine at California Institute of Technology."

Information on Instrumentation
For each of the instruments, please contact the indicated GLA for training or troubleshooting.
The Protein Expression Center (PEC) in the Beckman Institute (room 286) has a new cell disruptor that is free to Signaling Center users. The cell disruptor is a Constant Systems TS Series Benchtop model. Compared to a microfluidizer, this instrument can reach higher pressures for yeast lysis (and easily be used at lower pressures for bacteria). The instrument is equipped with a circulating chiller for cooling to desired temperature, i.e. 4 degrees Celsius. Contact Andrea Kuipers, BI 202, extention x3568, to set up training (akuipers@caltech.edu). You will be asked to set up an online account with PEC and then submit an order online for training or cell disruptor use. On the site, select the "Protein Downstream Processing" and the "Cell lysis" options. Use of this cell disruptor will be free for Signaling Center users with user fees charged to group-specific Signaling Center PTAs.
