<!--
For simplicity and to avoid redundancy, this section would contain only terms that are specific to [[DNA Microarry]], but would not be suitable in [[Glossary of gene expression terms]], or in a more general glossary.

* An ''array'' or ''slide'' is a collection of ''[[Glossary of gene expression terms#F|features]]'' spatially arranged in a two dimensional grid, arranged in columns and rows.
* ''Block'' or ''subarray'': a group of spots, typically made in one print round; several subarrays/ blocks form an array.
* ''Case/control'': an experimental design paradigm especially suited to the two-colour array system, in which a condition chosen as control (such as healthy tissue or state) is compared to an altered condition (such as a diseased tissue or state).
* ''[[Channel (digital image)|Channel]]'': the [[fluorescence]] output recorded in the scanner for an individual [[fluorophore]] and can even be ultraviolet.
* ''Dye flip'' or ''dye swap'' or ''[[fluorophore|fluor]] reversal'': reciprocal labelling of DNA targets with the two dyes to account for dye bias in experiments.
* ''Scanner'': an instrument used to detect and quantify the intensity of fluorescence of spots on a microarray slide, by selectively exciting fluorophores with a [[laser]] and measuring the fluorescence with a [[filtered|filter (optics)]] [[photomultiplier]] system.
* ''Spot'' or ''feature'': a small area on an array slide that contains picomoles of specific DNA samples.
