Experiment Overall Design: There are 6 control chips and representing animals treated with vehicle control. There are 3 biological replicates (3 chips) for each treatment group (eg. TCDD, PCB126), each biological replicate is derived from 2 individual animals. A total of 21 chips were analyzed. Intensities were normalized using the GC-Robust Multiarray (GCRMA) method through Genetraffic software package.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-5789", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-5789/samples/"}
