The phrase "quantified expression of" is correct and can be used in written English.
You could use it in a sentence like this: "I needed to provide a quantified expression of my opinion about the issue." This sentence means that you needed to provide a numerical value or a clear amount that represented your opinion about the issue.
We quantified expression of 11,873 genes in paired samples of primary leukemia cells and normal leukocytes from 92 patients with acute lymphoblastic leukemia (ALL).
We quantified expression of these adhesion markers to detect age-related differences in PMN functional efficiency.
OB conducted the microarray analyses and, together with JEL, quantified expression of FIL-response genes by qRT-PCR.
We quantified expression of the genes described above in ten paired frozen tumor and non-neoplastic prostate tissues.
We therefore quantified expression of components of the insulin signaling pathway in frataxin-transgenic animals before and after exposure to doxorubicin.
We quantified expression of previously annotated miRNAs from miRBase (Griffiths-Jones et al. 2008; www.mirbase.org, release 15) for human, chimpanzee, and rhesus macaque.
In each such splicing event, we may characterize the splicing decision in terms of the inclusion ratio, defined as the ratio of quantified expression level of the inclusion isoform divided by the sum of quantified expression levels of both inclusion and exon-skipped isoforms.
Quantified expression levels of each target gene were normalized to those of tubulin as a control.
We quantified expressions levels of the CC chemokines, MCP-1 and RANTES and the CX3C chemokine, fractalkine, all of which are chemoattractant factors involved in monocyte recruitment.
We analyzed gene expression data of two large cohorts of CLL patients and quantified expression variability across individuals to investigate differences between the two subtypes using different measures and statistical tests.
To validate these data, we analyzed levels of Nuc-Stat5a with immunofluorescence and quantified expression with AQUA in a tissue microarray from an independent cohort of adjuvant therapy-naïve, node-negative breast cancer patients (Material IV).
