Kinetics of actin polymerization in WAS and XLT neutrophils.

Actin polymerization in WAS (○), XLT(⧫), and control (▴)neutrophils in response to stimulation with FMLP (A), IB4 (B), 3G8 (C), PMA (D), or buffer control (A-D, ▪). Error bars represent SEM of duplicate simultaneous determinations for a single donor (control, WAS, or XLT). These graphs are representative of data collected from 2 patients with WAS, 3 patients with XLT. and at least 5 control donors.
