Key points of the analysis of microarray – 基因芯片分析要点

biological replicates – 生物学重复
Five or more is usually robust for micro-array studies
五个及以上的样本数对基因芯片研究来说才是具有鲁棒性的。
qPCR validation
Micro-array may give many false positives so it is usually necessary to validate the differential expression observed in some of the key genes.
基因芯片可能产生许多的假阳性结果，所以验证部分关键的差异表达基因通常来说是必须的。
