Molecular immunology techniques unpack the molecular machinery of immune responses using modern laboratory methods. This book begins with an accessible primer on immune cell types and signaling pathways, then transitions into hands-on protocols: PCR-based assays, flow cytometry panels, ELISAs, single-cell sequencing, and CRISPR editing for immune targets. Each protocol includes reagent lists, stepwise instructions, common pitfalls and troubleshooting tips, plus guidance on experimental design and controls to ensure reproducible results. Data analysis chapters cover gating strategies, normalization, and statistical interpretation for immunology datasets. Safety, biosafety level considerations, and ethical use of samples are emphasized throughout. It's an essential lab companion for immunologists, molecular biologists, and advanced students.
