Proteome Science

Table 3 The estimated minimal sample number per group for five proteins based on western blot, where power is the power of statistical test, α is the significance level, and π refers to the estimated proportion of truly differentially expressed proteins among all of the identified proteins.

From: An individual urinary proteome analysis in normal human beings to define the minimal sample number to represent the normal urinary proteome
