This book is designed to be a practical progression of experimental techniques an investigator may follow when embarking on a biochemical project. The protocols may be performed in the order laid ottt or may be used independently. The aim of the book is to assist a wide range of researchers, from the novice to the frustrated veteran, in the choice and design of experiments that are to be performed to provide answers to specific questions. The manual describes standard techniques that have been shown to work, as well as some newer ones that are beginning to prove important. By following the prominently numbered steps, you can \vork your way through any protocol, whether it’s a new technique or a task you‘ve done before for which you need a quick review or updated methodology.
This manual will assist the experimentalist in designing properly controlled experiments. There will be no advice for dealing with specific pieces of equipment other than encouragement to read the manual. if you can find it. Through out all manipulations try to be objective. Be on the lookout for unexpected findings. You will learn the most from unexpected results. and they are often the beginning of the next project. It is never possible to record too much in your lab notebook. Do not get discouraged. Remember, things will not always run smoothly.
