NCIt related terms : Two-channel Microarray; Dual-channel Microarray; Two-channel Expression Array; TWO-COLOR MICROARRAY; Two-color Microarray-based Gene Expression;
NCIt definition : A genomic microarray-based method using cDNA from two samples, labeled with two separate
fluorophores/dyes at different emission wavelengths, and hybridized to a single microarray
for laser excitation in a microarray scanner. Relative fluorescence intensity of each
dye can be measured and used in log- or intensity- ratio based comparative analysis
for gene expression between the two experimental conditions.;
Alternative definition : CDISC: A genomic microarray-based method using cDNA from two samples, labeled with
two separate fluorophores/dyes at different emission wavelengths, and hybridized to
a single microarray. The relative fluorescence intensity of each dye is being measured.;
