Rate of B cells and subsets change with age in vivo. a Rate of B cells in peripheral blood in cell number per μl blood. The rate of B cell was calculated based on flow cytometry analysis using the gating strategy described in (Additional file 1: Figure S1) and lymphocyte counts from complete blood (N = 162). b Rate of naïve B cells in B cell in cell number per μl blood (N = 218). Naïve B cells were defined by CD19+IgM+CD27-. c Rate of memory B cells in B cell in cell number per μl blood (N = 162). Memory B cells were defined by CD19+CD27+
