Sentence examples for microarray expression measurements from inspiring English sources

For example, background levels of hybridization (i.e. hybridization to a probe that occurs irrespective of the corresponding transcript's expression level) limit the accuracy of microarray expression measurements, particularly for transcripts present at low abundance.

Real-time PCR confirmed microarray expression measurements of selected genes.

The correspondence between the qRT-PCR and microarray expression measurements is shown in Figure 1.
