I'm writing a paper in which the experimental results with two different antibodies are compared across different brain regions.
I want to write something like:
We used antibodies A and B for this experiment. We obtained distinct results depending on the antibody and brain region.
Here each experiment only uses either one of the two antibodies.
I wonder if "depending on" should be followed by "the antibodies and brain regions" (the + plural) or "the antibody and brain region" (the + singular).
Actually, I have no problem with "depending on antibody and brain region", i.e. uncountable and abstract use of nouns without an article. This kind of example phrase can be found in dictionaries.
However, as soon as there comes a "the", I cannot really tell what is right.
If I consider the following sentence,
We obtained distinct results depending on the antibody and brain region examined.
then "the + singular" sounds natural to me, for only one antibody or region can be examined at one time.
Could someone please give me some advice on this?
