摘要:
A method screens compounds out of the group consisting of proteins, peptides, peptidomimetics, antibodies and small organic molecules that increase the activity of the protein Rac1 by virtue of their binding to the extracellular portion of this protein. The method includes the steps of: contacting a confluent layer of cultured endothelial cells with at least one of test compounds, lysing the endothelial cells with a lysation buffer, and measuring the amount of Rac1 activity.
