Quantitative changes in differentially expressed proteins in controls versus heroin addicts.

Spot numbers correspond to the same numbers shown in Figure 1. Spot density is the average OD of the same spot from three independent samples belonging to the same experimental group. CV shows spot OD variation across these three samples.斑点编号与图1中所示编号保持一致。斑点密度指同一实验组的三个独立重复样本中，同一斑点的平均光密度(Optical Density, OD)。变异系数(Coefficient of Variation, CV)用于反映这三个样本间同一斑点的光密度变异程度。
