Gene microarrays hybridization

Microarray hybridization is a process by which nucleic acids are detected by hybridizing with complementary sequences bound to wafers at specific array coordinates. Hundreds to thousands of gene products may be measured in a single experiment.

Our data indicate that the formation of somatic globular embryos is accompanied by the accumulation of storage protein transcripts. Figure 9.6 illustrates that transcripts for the synthesis of gibberellic acid also accompany the formation of somatic embryos. These microarray hybridizations experiments have been entered into the GEO (Gene Expression Omnibus) database of NCBI at http //www.ncbi.nlm.nih.gov/geo.

There are many protocols and different types of platforms available, e.g. GeneChips from Affymetrix, Illumina Bead Arrays, Arrays from Agilent, Applied Biosystems, GE Healthcare, customized spotted cDNA microarrays etc. the basic procedure for a large-scale measurement of gene expression involves the preparation of total or mRNA from the biological sample(s) under investigation (e.g. candidate tissue) and the hybridization of copied labelled RNA or cDNA to the DNA elements on the array surface (Fig. 1).
