| Assay sensitivity | Assay sensitivity is a property of a clinical trial defined as the ability to distinguish an effective treatment from a less effective or ineffective treatment. Assay sensitivity is important in any trial but has different implications for trials intended to show differences between treatments (superiority trials) and trials intended to show non-inferiority. If a trial is intended to demonstrate efficacy by showing superiority of a test treatment to control lacks assay sensitivity, it will fail to show that the test treatment is superior and will fail to lead to a conclusion of efficacy. In contrast, if a trial is intended to demonstrate efficacy by showing a test treatment to be non-inferior to an active control, but lacks assay sensitivity, the trial may find an ineffective treatment to be non-inferior and could lead to an erroneous conclusion of efficacy.

| Clonogenic assay | Clonogenic assay is a microbiology technique for studying the effectiveness of specific agents on the proliferation of cells. It is frequently employed in cancer research laboratories to determine the effect, if any, of a drug, radiation, or a combination of both on proliferating tumor cells. The term "clonogenic" refers to the fact that these cells are clones of one another. (references) | ||

| Overlay assay | An overlay assay is a biological technique used to find proteins that bind to a protein of interest. It begins with proteins that are dispersed but fixed (e.g. a tissue slice or run on a membrane by gel electrophoresis) and then incubated in the labelled protein of interest. The label will indicate the location of proteins that bind to the protein of interest. (references) | ||
| Reporter gene assay | Reporter gene assay is an analysis method that allows the identification of promoters and enhancers and the study of the correlations between their activities and conformations by checking the amount of the reporter proteins that are expressed from reporter genes. The promoters and the enhancers, which are upstream of all protein coding regions on the genome, adjust the activity and enhancement of the expression of the proteins. Because the reporter genes that code useful proteins that become indicators later in the target cells are artificially built downstream of the promoters and enhancers, reporter genes have become a focus of investigations.

| TUNEL assay | Terminal transferase dUTP nick end labeling (TUNEL) is a common method for detecting DNA fragmentation that results from apoptotic signaling cascades. The assay relies on the production of nicks in the DNA which can be identified by terminal transferase, an enzyme that will catalyze the addition of dUTPs that are secondarily labeled with a marker. In combination with whole mount immuno-cytochemistry or flow cytometery, this assay reproducibly labels cells in the final stages of apoptosis. (references) | ||
