Oligonucleotides attach to plates {array} in rectangular patterns, to test one sample for hybridization.
plates
Plates can be silicon chips {DNA chip}, plastic blocks with small wells {microarray, plate}, optical-fiber tips {bead array}, or glass slides {planar array}.
process
For example, plastic blocks have wells. Wells have reactive-chemical solutions to assay samples. Array probes samples by hybridizing oligonucleotides to sample RNAs or cDNAs. Reader detects hybridization amount using light. Statistical and comparative calculations follow.
Sample plates {master plate} stored in freezers can make daughter plates.
Master plates supply other plates {daughter plate}.
Arrays {microarray} can have 9x9-spot matrices at hundreds of positions, to test many genes against one or more test oligonucleotides, plus controls and fiducial-probes.
Plates {microtiter plate} can have small wells.
Sample plates contain pits {well, array} that can hold one or more samples.
