描述----------Description----------
This ExpressionSet object contains a subset of the microarray data used in References for PLGEM set-up and validation. Briefly, it contains normalized gene expression values from a total of 6 hybridizations on MG-U74Av2 Affymetrix GeneChip microarrays. Two experimental conditions are represented in this dataset: the baseline condition ("C") contains data of immature murine dendritic cells (4 replicates); the other condition ("LPS") contains data of the same cells stimulated for 4 hours with LPS (2 replicates).
这ExpressionSet对象包含在为PLGEM设置和验证的参考使用的芯片数据的一个子集。简言之,它包含了归一共有6对MG-U74Av2 Affymetrix基因芯片杂交的基因表达值。两个实验条件在这个数据集表示:基线条件(“C”)包含未成熟小鼠树突状单元的数据(复制),包含4小时刺激的相同单元中的数据的其他条件(脂多糖) LPS(复制)。
