Rac expression in human erythrocytes. (A) Proteins extracted from of 5 × 107 erythrocyte membranes were hybridized with a monoclonal antibody specific for Rac1 (R1-ab#2). The signal was detected at about 21 kDa, as expected. (B) In a different gel, same amounts of erythrocyte membranes were probed with the monoclonal anti-Rac2 specific antibody; no signal was detected. The same filter was then probed with an anti-Rac antibody (recognizing Rac1-3 proteins) (R1-ab#1), used as a loading control (bottom). The full lanes are shown in Fig. S10.
