The phrase "assays were completed using a" is correct and usable in written English.
It can be used in scientific or technical contexts when describing the methods or materials used to conduct assays.
Example: "In our study, assays were completed using a standardized protocol to ensure accuracy and reliability."
Alternatives: "assays were performed with a" or "assays were conducted using a".
To this end, a number of phenotypic assays were completed using a series of strains harboring wild-type H2B, H2B K37A, H2B K37R, or H2B K123R mutant histones (in most cases, except where specifically noted, the H2B K123R mutant strain was included as a positive control).
For rice tissues, GUS staining assays were completed using a modified GUS buffer [ 93] brought to pH 7 [ 94], and chlorophyll was removed from the tissues as described by Cervera [ 95].
For each reporter, a minimum of three independent frameshift assays were completed using different preparations of mRNA (full biological replicates).
Proliferation assays were completed using the sulforhodamine B (SRB) colorimetric assay as described previously (Vichai and Kirtikara, 2006).
Measurement of sE-selectin was completed using a high-sensitivity ELISA assay (Parameter Human sE-Selectin Immunoassay, R&D Systems).
The RT-qPCR assay was completed using duplicates of each sample.
Measurement of sICAM-1 was completed using an ELISA assay (Parameter-Human sICAM-1 Immunoassay; R&D Systems).
Allele identification of the one nonsynonymous SNP in FUT2 that accounts for >95% of the incidence of nonsecretor phenotype in Caucasians was completed using an ABI Taqman assay.
Short-term adhesion assays (30 minutes) were completed using the calcein-AM (Life Technologies, Mulgrave, Victoria, Australia) labelling method as described previously (Chia et al., 2007).
Additionally, the coupling and electron flow assays could be completed using one micro titer plate with various inhibitors and uncouplers in a single mitochondrial isolation.
Reverse transcriptase was heat inactivated at 94°C for 4 min. Q-PCR of specimen and standard cDNA was completed using TaqMan predeveloped assay reagents.
