Abstract

This document reproduces the Figures presented in (2016). For a description of the theory behind applications shown here we refer to the original manuscript. The results differ slightly due to technical changes or bugfixes in msqc1 that have been implemented after the manuscript was printed.

Package

msqc1 1.28.0

1 Introduction

Here we provide an experiment data package containing all the spread sheets used for figures and supplemental figures published in Kockmann et al. (2016). The raw instrument files are accessible for registered users through https://fgcz-bfabric.uzh.ch (2022) as project 1959. Raw LC-MS data from all five platforms were imported into Skyline 3.1, see MacLean et al. (2010), processed, and are available though https://panoramaweb.org/labkey/MSQC1.url when published. This package contains data.frame objects exported by Skyline making the data available for the R world.

2 MSQC1 Peptide properties

2.1 Figure - reference L:H ratio versus the on-column amount

The scatter-plot displays the reference Light:Heavy ratio versus the on-column amount of heavy peptide of the MSQC1 peptide mix. Note, x and y axis are drawn in log scale.
