Fig. 4.
CD34+ PBMC express cytoplasmic Ig. PBMC were stained with anti-CD34, followed by ethanol permeabilization and staining with FITC-coupled F(ab)2 fragments of anti-human Ig, or anti-mouse Ig (control). The thin line represents control staining and the thick line represents staining with anti-human Ig. Intensity of staining is on a log scale.
