Fig. 4. Co-immunoprecipitation of RhoA and RhoGDI. (A) RhoA antibody was incubated
with cell lysate from control and forskolin-stimulated CD8 cells.
Immunocomplexes were precipitated with Protein-A-conjugated agarose. Proteins
were eluted using Laemmli buffer and analyzed by immunoblot for detection of
RhoGDI. This result is representative of three independent experiments
demonstrating that forskolin stimulation is associated with the formation of a
soluble RhoA-Rho-GDI complex. (B) Densitometric profile (mean
values±s.e., n=3) of the 29 kDa band.
