CD19⁺ populations in transgenic lymph nodes.

FACS analysis of CD19⁺ populations in mesenteric lymph nodes from control and transgenic mice analyzed for coexpression of CD5 (A) or CD34 (B) surface antigens. Light scatter plots (C) are also shown with important gates indicated (R1 = total leukocyte gate, on which the fluorescent plots were gated; R2 = increased granular population identified in the transgenic mice). Percentages for all fluorescent populations are indicated. Data are representative of one animal per plot.
