The phrase "assayed for several" is correct and usable in written English.
It can be used in contexts where you are discussing the testing or analysis of something for various purposes or conditions.
Example: "The samples were assayed for several key components to determine their quality and effectiveness."
Alternatives: "tested for several" or "analyzed for several".
All BioGel fractions (10 μL/assay, in duplicate) were assayed for several enzymes common to most rattlesnake venoms [ 21], including exonuclease (phosphodiesterase), L-amino acid oxidase, caseinolytic metalloproteinase, thrombin-like and kallikrein-like serine proteinases and phospholipase A2, as described previously [ 47].
Recently, I reported on a set of assays for several DNA-modifying enzymes (polymerases, endonucleases, and ligase) based on simple, hairpin-type oligonucleotide substrates labeled with a single fluorophore (Anal. Biochem. 412 (2011) 229 236).
To verify that the microarray data are reliable, we performed real-time PCR assays for several mRNAs whose levels in microarrays were affected by the various treatments.
These include assays for several flaviviruses [ 10, 15, 16], and 16S rRNA assays [ 12] for several bacteria.
Serologic testing (indirect immunofluorescence and virus neutralization assays) for several alphaviruses were performed as described (1 ), and the results (Table) confirmed our presumptive diagnosis.
Immunohistochemical assays for several organisms were performed at CDC; the results were negative for hantavirus and spotted fever group rickettsiae, while immunohistochemical assay for leptospira showed granular immunostaining in the renal biopsy to confirm the diagnosis of leptospirosis.
Selected samples (12 PD and 12 HC blood samples) previously processed for gene expression profiling were also tested in RT-qPCR assays for several targets (CBX5, HELLS, MECP2, ASF1A, DNMT3A and PRMT1) that were identified by data analyses.
The ability of DIR proteins to direct the stereoselective formation of lignans has been previously demonstrated with in vitro assays for several members of the DIR-a subfamily from Forsythia intermedia [ 37].
In the dose response assays for several mutants, we observed that the Phe288Ala, Trp299Leu, and Leu308Phe PXR mutants were weakly activated by BPA at high concentrations (e.g., 25 or 50 μM); however, the Ser247Ala, Ser247Leu,, and Tyr306Phe mutants were inactive even at these concentrations.
In the present study, a panel of 1,152 EST-derived SNPs was selected from the Sigenae SNP database and were subsequently assayed for allelic variation in several rainbow trout population samples using the Illumina GoldenGate assays.
Importantly, the same trends were observed for two different inducers of mitotic death (Cdc20 knockdown and treatment with vinblastine), for two independent cell death assays and for several different clonal cell lines of each type.
