Single Array for Human Genome Expression Analysis
GeneChip® brand Human Genome U133 Plus 2.0 Array provides the protein-coding content of the human genome on a single microarray. The HG-U133 Plus 2.0 Array analyzes the expression level of nearly 50,000 RNA transcripts and variants with 22 different probes per transcript. The product puts about 1.3 million probes on a chip the size of a human thumbnail. Multiple independent measurements for each transcript ensure that data quality remains high, even as data capacity increases. Data is verified against the latest version of the publicly available genome map. Probe design strategy is identical to the previous HG-U133 Set, providing strong data concordance between the two products. HG-U133 Plus 2.0 Array uses 22 independent measures to detect the hybridization of each transcript on the array, 1.3 million data points in all. Using multiple, independent measurements provides sensitivity and specificity.
