A panel of skilled researchers describes in step-by-step detail their best laboratory techniques for elucidating liposome biology. With these readily reproducible methods, investigators can illuminate such critical questions as the attachment of liposmes to cell surfaces, the permeation of liposomes through the plasma membranes, and the stability of liposomes in cellular and nuclear matrices. Each detailed protocol is presented by an investigator who is intimately familiar with its problems and capabilities, and includes a detailed list of materials to be used, troubleshooting tips straight from the benchtop, and notes on pitfalls to avoid.
