Product Uses Include
- The combo kit is an ideal choice when your experimental observations suggest that one or more Rho family proteins are activated.
- Provides 10 assays each for detection of activated RhoA, Rac1, and Cdc42.
- Includes an extensive array of reagents (see kit contents below).
- Most cost effective way to obtain a Rho family activation profile.
Assay Principle
The assay is based upon the fact that a Rho family effector protein is known to bind preferentially to the active (GTP-bound) form of its target GTPase (1). In the case of RhoA activation, the rhotekin-RBD effector domain is used to make the affinity beads (2). In the case of Cdc42 and Rac1 activation, the PAK-PBD effector domain is used for affinity beads (3).
