Gene expression analysis is currently performed with the Affymetrix genechip technology. Oligonucleotide arrays are designed by Affymetrix and are synthesized based on sequence information available in public databases. To monitor gene expression, the mRNA from cells or tissue is biotin-labeled and hybridized to chips containing the oligonucleotide arrays. The specificity of hybridization is measured by laser confocal fluorescence scanning. This technology allows massive, parallel data acquisition and analysis.

** There are various types of service provided within the Gene Expression section. These consist of Full Service (including sample QCs using Bioanalyzer and Nanodrop), Hybridization and Scanning, and Bioanalyzer QC. Please find the appropriate sample submission requirements for each type before submitting your orders.
