How can you use “two-color” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • To assist in identifying regions of unidirectional gene-expression bias, we have constructed a web-based program that processes two-color gene-expression data and identifies genomic regions that contain gene-expression biases.

  • In the workflow above, an Array and one or more BioMaterials (for two-color microarrays this would be two Labeled-Extracts) are combined to create a PhysicalBioAssay.

  • Examples of some of the uses and technologies supported include: one- and two-color spotted arrays (cDNAs, PCR products, or oligonucleotides) on glass or nylon, in situ synthesized oligonucleotides (Affymetrix/photolithography, ink-jet), RNA abundance (gene expression, polysome profiling), and DNA abundance (array-CGH, chromatin immunoprecipitation, genotyping).

  • The results for each spot (or gene) include an absolute call of present (P) or absent (A) (a call of present indicates that the signal was greater than the regional background AND greater than the local background measured in the four corners surrounding the individual spot), the scaled intensity, the difference between the scaled fluorophore intensities, the fold change or ratio of the two-color intensities (expression ratio), and a qualitative difference or change call of I, MI, D or MD (change calls are based on the fold changes across the duplicate spot data).

  • For multi-BAC (two-color) FISH, biotinylated probes were detected with FITC avidin and digoxigenin-labeled probes were detected with Rhodamine anti-digoxigenin (Roche).
