Rac1 is a member of the expanding family of Ras-related GTPase proteins. These
small proteins have the ability to switch between two different conformational
states: the active (GTP-bound) and the inactive (GDP-bound). The GTPase
activity is increased by specific activator proteins named GAPs. Rac1, contains
the consensus sequence Cys-X-X-X-COOH, which localizes it to the plasma
membrane. Growth factor stimulation of cells results in a dramatic reorganization
of the actin filament network and membrane ruffling, processes for which Rac1 is
essential. Constitutive expression of Rac1 leads to cell transformation. This
process is mediated by the Rac1-dependent activation of the p65PAK
serine/threonine kinase. IQGAP1 has been identified as a GTPase activating
protein specific for Rac1.
Testing in native ELISA with recombinant proteins to CDC42 and Rho have shown
that the antibody to Rac1 (cat No 610650/1) recognizes CDC42 and Rho. Due to
sequence homology among various small GTPase familyl members, potential
reactivity could be observed with other family members.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
