This volume provides key methods and protocols from laboratories engaged in germinal centers (GC) research with the expectation of stimulating further research, and to aid scientists in the study of GC biology and pathology. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
