Affymetrix GeneChip Instrument System

eagle-i ID


Resource Type

  1. Microarray platform


  1. Resource Description
    "Gene expression profiling or microarray analysis has enabled the measurement of thousands of genes in a single RNA sample. GeneChip microarrays are manufacture by photochemical synthesis. Because of this manufacturing technology, more than a million different probes can be synthesized on an array roughly the size of a thumbnail. These numbers allow the inclusion of multiple probes to interrogate the same target sequence, providing statistical rigor to data interpretation. Over the years the GeneChip platform has proven to be a reliable and robust system, enabling many new discoveries and breakthroughs to be made by the scientific community. After hybridization of the biotinylated sample, the chip is stained with streptavidin-phycoerythrin and read with a confocal scanner. Control and experimental samples are hybridized to separate chips. Comparison of the two chips is performed to determine the differential gene expression levels of the two compared samples."
