Microarray Background Allows researchers to analyze the expression of thousands of genes at one time. This technique can be used to identify and analyze mutations in DNA Model organisms, whose genome has been completely sequenced, are used in microarray experiment.
First Microarray Experiment • Was performed by researchers from the NIH, Stanford University, and others • Wanted to compare gene expression of patients with B-cell Lymphoma • Patients fell under two categories: • Long-term survivors • Short-term survivors
