GEArray DNA Microarrays are ideal tools for your gene expression studies. Each GEArray includes a thoroughly researched set of relevant, pathwayor disease-focused genes. GEArray is the most sensitive microarray. It is easy to use and reliable. Choose from our comprehensive list of standard GEArrays covering applications including cancer, immunology, apoptosis, cell signaling and more. Or order a custom GEArray tailored to your special application. GEArrays are priced from $50/array. Pathway focused design: The design reflects the most current understanding of pathways and functionally related gene families. Sensitive and reproducible: Requires as little as 0.1 micrograms total RNA. Designed for routine use: GEArrays can be used in any lab; a thermal cycler, hybridization oven, and X-ray film or CCD imager system are the required equipment. Can be detected by either chemiluminescence or fluorescence. Complete microarray hybridization/analysis service also available. Let us show you what focused microarray technology can do for you.
