Description

General description

QCAL was designed using the QconCAT technology and recombinantly expressed in E. coli.  The parent protein sequence of QCAL is as follows:

QCAL was subsequently digested with trypsin to give a core mixture of 22 peptides.

Application

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

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.
