Its coverage includes cell and molecular biology, genetics, bioinformatics, protein science, and imaging. Protocols are presented step-by-step and edited in the style that has made Molecular Cloning, Antibodies, Cells and many other CSH manuals essential to the work of scientists worldwide. Protocols will be continuously expanded, updated, and annotated by the originators and users of the techniques."
