The second edition of Adhesion Protein Protocols combines traditional techniques with cutting-edge and novel techniques that can be adapted easily to different molecules and cell types. The topics discussed include novel techniques for studying cell-cell adhesion, neutrophil chemotaxis, in vitro assays used to study leukocyte migration through monolayers of cultured endothelial cells, and novel techniques to purify pseudopodia from migratory cells. The protocols discussed in this volume are suitable for both novice and expert scientists, who will gain further insight into the complex and incompletely understood processes involved in cellular adhesion.
