A MACS protocol for purification of untouched germinal center B cells from unimmunized or germinal center-induced mice
Abstract
Summary: Highly enriched germinal center (GC) B cell populations are essential for studying humoral immunity. Current MACS protocols that isolate untouched GC B cells require GC induction and typically require further FACS purification with direct antibody labeling to achieve sufficiently high purities. We present a MACS protocol with progressive and repeated negative selections that yields highly purified untouched GC B cells from both unimmunized and GC-induced mice and allows further FACS isolation of unlabeled GC B cells from remaining debris by scatter. : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
