Analysis of spleen leukocyte subpopulations by FACS. Splenocytes were collected from WT and homozygous B-hCD32B mice (n=3, 7-week-old). Flow cytometry analysis of the splenocytes was performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live cells were gated for the CD45+ population and used for further analysis as indicated here. B. Results of FACS analysis. Percent of T cells, B cells, NK cells, dendritic cells, granulocytes, monocytes and macrophages in homozygous B-hCD32B mice were similar to those in the C57BL/6 mice, demonstrating that introduction of hCD32B in place of its mouse counterpart does not change the overall development, differentiation or distribution of these cell types in spleen. Values are expressed as mean ± SEM.

Analysis of spleen T cell subpopulations by FACS. Splenocytes were isolated from female C57BL/6 and homozygous B-hCD32B mice (n=3, 7-week-old). Flow cytometry analysis of the splenocytes was performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live CD45+ cells were gated for CD3+ T cell population and used for further analysis as indicated here. B. Results of FACS analysis. The percent of CD8+ T cells, CD4+ T cells, and Tregs in homozygous B-hCD32B mice were similar to those in the C57BL/6 mice, demonstrating that introduction of hCD32B in place of its mouse counterpart does not change the overall development, differentiation or distribution of these T cell subtypes in spleen. Values are expressed as mean ± SEM.

Analysis of blood leukocyte subpopulations by FACS. Blood cells were collected from WT and homozygous B-hCD32B mice (n=3, 7-week-old).
