1. Has anyone else already published essentially the same experiment? If
so, you need to seriously reevaluate your experimental plans. If not,
proceed to step 2.
2. What are the possible outcomes of the experiments?
3. How many times will you need to repeat individual experiments to
achieve statistical significance?
4. What controls (both positive and negative) do you need to run in each
experiment?
5. How will you present the results of these experiments (as a table, bar
graph, photomicrograph, etc.)?
6. How many experiments will be required to support a positive or nega-
tive conclusion?
Develop a list of the “take home” messages you will be able to support with
either a positive or negative outcome to your proposed experiments. This
will serve as a basis for your final conclusions and discussion.
Consider each manuscript in the context of your laboratory’s resources,
focusing on people, time, and money. You are advised to coordinate com-
pletion of the manuscript with the timelines of your key personnel. For
example, if the first author on your study is a senior student who is prepar-
ing to defend his or her thesis, try to get all of the manuscripts submitted
prior to the student’s graduation date. This way, if the journal reviewers
request additional experiments prior to acceptance, you are positioned more
favorably to meet their demands. It is more difficult to complete the writing
of manuscripts (much less to perform further experiments) once a graduate
student has moved out of your laboratory for postdoctoral training.
Each manuscript represents a significant allocation of financial
resources. Take the time to evaluate whether the paper has paid for itself by
calculating the salaries of the personnel involved, the supplies and reagents
used, and the page charges from the journal; the latter can be substantial if
your figures are in color. The expenses (and their sources) may surprise you.
Whenever possible, a manuscript should serve the needs of your laboratory’s
existing grants by documenting your completion of a specific aim or of
future grant applications by generating supportive preliminary data. The
research within the manuscript should open doors to new research oppor-
tunities rather than lead to a “dead end.”
Consider the audience and “impact factor” of the journals in which you
would like to publish your manuscript. You should try to publish your work
in a journal that will best reach the scientific community most closely
involved with your research activities. If possible, try to publish in a jour-
nal that will also expose your work to investigators beyond your immedi-
ate field. One way to gauge whether a journal is widely read is through its
impact factor. Thomson-ISI (http://www.isinet.com/) calculates each
