Fig. 7From: Development of robust targeted proteomics assays for cerebrospinal fluid biomarkers in multiple sclerosisCalibration curve for the peptide YEVSSPYFK from the protein Cadherin-13 in rat plasma. Blank values (blue) indicates abundance of background without spike-in of endogenous peptide but spike-in of heavy. Spiked samples (green) have both endogenous and heavy spike in. The linearity of the lowest concentrations is shown in the smaller graph for increased visibility. The experiments were conducted in trypsinated triplicates. The figure was created using R (http://www.R-project.org) and ggplot2 (https://ggplot2.tidyverse.org)Back to article page
