Hands-on laboratory experts describe for the novice investigator a host of novel technologies and molecular techniques specifically designed to study cellular immunology and promote its gene therapy applications. Presented in step-by-step detail to ensure ready reproducibility, these protocols range from flow cytometric techniques to detect cytokines and growth factors in different specimens, to methods for generating and expanding dendritic cells and hematopoietic progenitors from different origins. Although the protocols require little previous experience, even highly skilled researchers will augment their skills with many novel timesaving techniques.
