Fig. 8From: Random and independent sampling of endogenous tryptic peptides from normal human EDTA plasma by liquid chromatography micro electrospray ionization and tandem mass spectrometryRegression analysis of the peptide-to-protein counts from samples incubated at room temperature (ALLRT) versus samples maintained on ice or frozen (ALLICE). Residual standard error: 2.945 on 22853 degrees of freedom, Adjusted R2: 0.3103, F statistic: 1.028e + 04 on 1 and 22853 DF, p-value < 2.2e − 16. To avoid infinity values 1 was added to each value (p1)Back to article page
