Relative expression of WASP family members and p34 in carcinoma cells. (A) Expression of N-WASP, WAVE1, and WAVE2 was detected in MTLn3 cells by RT-PCR on mRNA isolated from MTLn3 cells and positive controls (mixed population of rat mRNA). (B) Relative abundance of WASP family member mRNA was measured by quantitative real-time PCR.
