The phrase "assays were derived from" is correct and usable in written English.
It can be used in scientific or research contexts to indicate the source or origin of the assays being discussed.
Example: "The results of the study indicate that the assays were derived from a combination of previous research and new experimental data."
Alternatives: "assays were obtained from" or "assays were sourced from".
Results from real-time PCR assays were derived from at least three independent experiments.
Therefore, since hOSTs are known to express only type I, II and III collagens, we conclude that both the SHG images and hydroxyproline assays were derived from type I collagen only.
The flanking sequences for the SNPs used to build the genotyping assays were derived from the ongoing sequencing of the porcine genome by the Sanger Institute and these sequences are regularly uploaded to Genbank.
The most likely explanation for this phenomenon is that these assays were derived from multicopy genes and we mapped different paralogs in different crosses.
The primer pairs to beused in the ChIP assays were derived from the PCR analysis of panels of gorilla, chimpanzee and human somatic cell hybrids (from M. Rocchi and [ 44]).
Spotting assays were derived from a pool of three independent fresh transformants.
The conditional medium used for in vitro wound healing assays was derived from fresh medium overlaid on wild type or Ikkβ −/− cells for 24 h.
Initially, we tested whether the signals found in in-gel protein kinase assays are derived from kinase auto-phosphorylation or due to trans-phosphorylation activities of the protein kinases.
Since the deletion of ILV3 gene in the haploid background strain BY4741 is lethal, the ilv3Δ mutant used in phenotype complementation assays was derived from the diploid parental strain BY4743 (MATa/a, his3Δ 1/his3Δ 1, leu2Δ 0/leu2Δ 0, lys2Δ0/ LYS2, MET15/met15Δ 0, ura3Δ 0/ura3Δ 0) with one copy of ILV3 deleted.
Further confidence in the specificity of the assays was derived from control sections of each clinical sample that were incubated with a dilution of primary antibody matched to that of the paired tests but preabsorbed for 5 hours with appropriate blocking peptide (one part antibody:three parts peptide).
Final datasets for each assay were derived from the mean values of three independent biological replicate experiments.
