We report a strategy for analysis of data quality in cDNA microarrays based on the repeatability of repeatedly spotted clones. We describe how repeatability can be used to control data quality by developing adaptive filtering criteria for microarray data containing clones spotted in multiple spots. We have applied the method on five publicly available cDNA microarray data sets and one previously unpublished data set from our own laboratory. The results demonstrate the feasibility of the approach as a foundation for data filtering, and indicate a high degree of variation in data quality, both across the data sets and between arrays within data sets.
我们报告了一种基于重复点样克隆的可重复性来分析cDNA微阵列数据质量的策略。我们描述了如何通过为包含在多个点上点样的克隆的微阵列数据开发自适应过滤标准,利用可重复性来控制数据质量。我们已将该方法应用于五个公开可用的cDNA微阵列数据集以及我们自己实验室的一个先前未发表的数据集。结果证明了该方法作为数据过滤基础的可行性,并表明数据质量在数据集之间以及数据集中的阵列之间存在高度差异。
