The phrase "assay upon" is not commonly used in written English and may not be considered correct in standard contexts.
It could be used in a scientific or technical context where "assay" refers to testing or analyzing something, but it is more typical to see "assay" used with "of" or "for."
Example: "The researchers decided to assay upon the new compound to determine its efficacy."
Alternatives: "test for" or "analyze".
We used fluorescence-quencher pair displacement assay upon progesterone binding for the determination of P4.
Deshielding was tested in vitro by zeta potential measurements and, erythrocyte aggregation assay upon addition of α-amylase (AA) to the HES-decorated particles.
Despite the presence of other unknown E. coli proteins in the crude fraction of rUbi with the actual concentration of rUbi being expected to be lower than the purified rUbi, the binding capability of αUbi is still unaffected as shown in phage ELISA assay upon affinity selection against crude rUbi.
In addition, caspase-3 activity was measured, using a fluorometric assay, upon exposure to bisphenol A (40 nM) alone, leptin (2.5 nM) alone, and the combination of both agents.
