Negative controls: untreated cells, empty vector control, and non-targeting control Negative control conditions and plasmids should produce a null effect (i.e., no phenomenon is observed). A negative control is an experiment that uses the same procedures as a primary experiment at the same time on a different population with a placebo or no treatment. 6. Unfortunately, a common "negative control" seen in many articles in the literature is to perform the immunohistochemical assay with a primary antibody in tandem with a specimen that is not exposed to the primary antibody; that is to say, with the primary antibody omitted.

Nonphysical goods, such as software, can be shipped electronically, eliminating the entire transport channel. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results.
