Agilent CGH Microarray Protocol

An Agilent Enzymatic Labeling Kit was used according to the manufacturer’s instructions to label 0.5 μg of genomic DNA for each CGH array. Labeled DNA was hybridized to an Agilent-022060 SurePrint G3 Human CGH Microarray 4x180K (Agilent Technologies, Inc., Santa Clara, CA, USA); the Agilent Microarray Scanner and Feature Extraction v.10.7.3.1 (Agilent Technologies), were used according to manufacturer’s instruction to scan probed arrays. Control DNA was obtained from one Japanese individual who is an author (MU) of this study. We focused only on previously reported SCNAs of CDKN2A [14 (link)] and on CNVs of UGT2B17 that are associated with metabolism of nicotine [15 (link)].
