Protocols described in Current Protocols in Cell Biology may include molecular biology techniques and biochemical techniques that are not fully described in this book. Although it may be reasonable to assume that cell biologists have at least a basic understanding of these techniques, there are times when a full step-by-step description of the procedure is helpful. This appendix lists techniques mentioned in this manual and provides specific cross-references to specific units in Current Protocols in Molecular Biology (CPMB) that describe the methods in detail.
