FACS Staining for Follicular Helper T Cells

Abstract

Germinal center is the primary site for B cells to undergo somatic hypermutation and class switching. A recently discovered subset of T cells known as T follicular helper (TFH) cells are essential for germinal center reaction and thus have been the subjects of intensive study in the recent years. This protocol describes a reliable way to stain this population for flow analysis. This protocol was developed or modified in Dr. Anne Davidson’s lab at Feinstein Institute for Medical Research.
