Application Note: High Throughput GEF Assay using the Transcreener GDP Assay
18 November 2014

This application note serves as a guide for using the Transcreener® GDP Assay to detect the activity of guanine nucleotide exchange factors (GEFs) based on their stimulation of steady state GTPase activity. As an example, an assay was developed using Dbs, a Rho-specific guanine nucleotide exchange factor (RhoGEF) in combination with two monomeric GTPases, CDC42 and RhoA.
