Bone marrow B cell flow cytometry results from a healthy donor. First, B cells were gated by using specific cell surface markers that were CD138⁺ and CD38⁺ by determining forward and side light scattering characteristics on the FACSAria II Cell Sorter (Becton Dickinson, San Jose, CA, USA). Then sorted B cells using with cell sorting by the cell surface markers CD56⁺, CD19⁺ according to the FACSAria II Cell Sorter.
