The Results section is the most important part of a paper. This is the core of the paper to which everything else relates, and should therefore be written first (or after you have warmed up on the methods), and with great care.
Organise all of your data into tables and figures (in logical order, not chronological order), before you start writing. Spread these out on a table, and describe the important results in each figure/table in point form.
The Results section must clearly outline the rationale or design of the experiments, and the experimental aims. You should introduce each experiment with a clear description of the experimental design and aims.
To detect proteins transiently expressed in prenatal brain, we compared the protein maps of both prenatal and postnatal brain.
The FG gene is only expressed at very low levels in the developing rat brain, so we used RT-PCR to detect FG expression in day 8 mouse forebrain.
We used a specific monoclonal antibody to determine the distribution of SOD expression in mouse kidney sections.
Then describe the data and the important findings or trends as concisely as possible. Lead the reader through each of the figures or tables.
The details of the methods are given in the Materials and Methods section, and should not be repeated in the Results section.
