The standard prools for the purification of all known cytoskeleton proteins are presented in this manual. Proteins are listed alphabetically and each prool follows a common format. Thus, the manual provides a quick and easy reference to all relevant procedures for cytoskeleton protein purification. The isolation procedure for each protein is shown in a clear flowchart, while the source of the protein, equipment and material needed, a list of suppliers, standard references, accession No. of sequences as well as further relevant facts and practical tips are given on a separate page.
