Flow cytometric protocol to characterize human memory B cells directed against SARS-CoV-2 spike protein antigens

Memory B cells (MBCs), part of the immune response elicited by infection or vaccination, can persist in lymphoid organs and peripheral blood and are capable of rapid reactivation upon secondary antigen exposure. Here, we describe a flow cytometric assay to identify antigen-specific MBCs from periphe...

Descripción
Sumario:Memory B cells (MBCs), part of the immune response elicited by infection or vaccination, can persist in lymphoid organs and peripheral blood and are capable of rapid reactivation upon secondary antigen exposure. Here, we describe a flow cytometric assay to identify antigen-specific MBCs from peripheral blood mononuclear cells and characterize their isotypes and activation status. We detail steps to use fluorescently labeled antigen probes derived from the SARS-CoV-2 spike protein. These can be adapted to detect MBCs against other antigens. For complete details on the use and execution of this protocol, please refer to Weskamm et al. (2022).(1)
