In this video, we describe a protocol for the flow cytometry-based sorting of naïve B cell, memory B cell, and plasmablast plasma cell subpopulations from human peripheral blood B cells. The different B cell subpopulations can be distinguished based on fluorophore-based antibody binding to the CD19, CD27, and CD38 receptors expressed on the B cell surfaces, followed by cell sorting.
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. Cell Sorting for the Collection of Naïve B Cells, Memory B Cells, and Plasmablasts/Plasma Cells (PBs/PCs) Using purified human peripheral blood B cells, determine the cell number using a hemocytometer or an automatic cell counter. <…
