The G-LISA activation assays are ELISA-based activation assays with which you can measure RhoA, Rac1, and Cdc42 activity in as little as 10 ug of cell or tissue lysates in less than 3 hours. These assays are very sensitive and have excellent accuracy between duplicate samples. For a more detailed introduction on G-LISA assays and a listing of other available G-LISA kits, see our main G-LISA page.
