Application

MSQC2 is intended to act as a universal MS platform standard, by providing several elements for calibration and performance assessment, such as instrument resolution and linearity of signal detection.

This product is optimized to assess platform characteristics, including:•Repeatability/Reproducibility between runs•System stability (drift, chromatography, signal intensity, sensitivity, etc.)•Inter- and intra- platform and lab comparisons

Components

Each vial contains 25 µg of lyophilized peptides that are derived from trypsin digestion of the protein concatamer QCAL.

Features and Benefits

GeneralComplexity Defined mixture gives confidence in your instruments analysis

General description

QCAL was designed using the QconCAT technology and recombinantly expressed in E. coli.  The parent protein sequence of QCAL is as follows:MGALRVFDEFKPLVEEPQNLIRVFDEFKPLVKPEEPQNLIRVFDEFKPLVKPEEKPQNLIRVFDEFKPLVKPEEKPQNKPLIRVFKPDEFKPLVKPEEKPQNKPLIRVFKPDEFKPLVKPEEKPQNKPLIKPRVFDEFQPLVEEPQNLIRGVNDNEEGFFSARGGVNDNEEGFFSARGGVNDNEEGFFSARGGVNDNEEGFFSARGGGVNDNEEGFFSARGGGVNDNEEGFFSARGGGVNDNEEGFFSARGGGVNDNEEGFFSARGGGVNDNEEGFFSARGVNDNEEGFFSAKGGGVNDNEEGFFSARAVMDDFAAFVEKAVMMDDFAAFVEKAVMMMDDFAAFVEKGLVKFVVPRALELFRIGDYAGIKEALDFFARYLGYLEQLLRVLYPNDNFFEGKLFTFHADICTLPDTEKALVALVLVPRGSLEVLFQGPIEGRTENLYFQGDDDDKALVALVHHHHHHQCAL was subsequently digested with trypsin to give a core mixture of 22 peptides.
