The phrase "an interaction assay" is correct and usable in written English.
It can be used in scientific or research contexts, particularly in biology or chemistry, to refer to a test or experiment designed to measure interactions between molecules or cells.
Example: "We conducted an interaction assay to determine the binding affinity between the two proteins."
Alternatives: "a binding assay" or "a reaction assay".
In an interaction assay shown in Figure 6(A), mutation of S158E greatly weakened the interaction between β1 and p27Kip1, but mutation of S158A shows an enhanced interaction of β1 with p27Kip1.
We excluded all annotations that were obtained by computational methods, and we also did not include GO annotations with evidence codes that suggest that the annotation was derived from an interaction assay (i.e. only the evidence codes EXP, IDA, IMP, IGI, IEP and TAS were included).
Therefore, an interaction assayed by use of these plasmids may sometimes escape detection.
However, in the case of the SH2-PLA, a protein interaction assay assessing phosphorylation of a target protein, preparation of a suitable control is not a trivial task.
In a pairwise interaction assay, these three proteins do not interact with any other Gerbera MADS domain proteins.
DOI: http://dx.doi.org/10.7554/eLife.00220.011 Next, we performed a qualitative interaction assay to determine whether agrin can interact independently with the APP ectodomain.
Growth was assayed on selective plates lacking tryptophan and leucine (–W, –L: transformation control) and interaction was scored on plates lacking histidine, adenine, leucine and tryptophan (–H, –A, –L, –W: interaction assay).
We used the drkEOA mutant, which loses binding to EGFR caused by mutation in the SH2 domain [39], for a genetic interaction assay.
Therefore, these inhibitors were added during a cell interaction assay), and either the parasite) or the macrophage) was treated with the inhibitors before the cell interaction assay.
We showed that these collections are functional by recombinant protein production in E. coli and by a protein interaction assay.
The cloning of 95% of the S. aureus ORFeome was achieved, and a random sampling of ORF-containing plasmid vectors showed the ORFs to be functional in two different downstream applications: recombinant protein production in E. coli and a protein interaction assay (Y2H).
