SHARE your operating (exact volumes,amounts,incubation times),so that your results can be reproduced by other chemists and biochemists.Usually,you will be borrowing the procedure from a lab manual,a textbook,or a journal article,so do not bother copying the whole thing out:it is sufficient to make reference to the source.However,any changes that you bring to that prescribed procedure must be mentioned here.
