Fig. 8From: Quartet protein reference materials and datasets for multi-platform assessment of label-free proteomicsAbsolute quantification of Quartet standards. A Workflows for absolute quantification (ABQ) of the Quartet. B Heatmap showing the linearity of peptide candidates as internal standards under a dilution series. C Response curves between ABQs and iBAQs of the anchor proteins (internal standard) in each sample of the Quartet (left), and dynamic ranges of ABQs (copy number/cell) for each sample of the Quartet (right)Back to article page
