WebExpression microarrays allow geneticists to determine which genes are on and which are off in specific cells, tissues, or organisms treated to different environmental conditions. To produce microarrays, sequences of genes are needed and microarrays can hold the sequences of an entire genome. WebMicroarray Gene Expression We performed microarray analysis with Affymetrix’s GeneAtlas ® System (Affymetrix Inc., Santa Clara, CA, USA). Firstly, total RNA samples were prepared from the three replicates of each control and EEA-SQ-treated hAEC sample (250 ng per RNA sample).
