This product is a mixture of 22 peptides derived from the post-trypsin digest of QCAL. This is a lyophilized powder. Upon reconstitution with an appropriate solvent - typically 0.1% formic or trifluoroacetic acid in water - the solution is injection-ready.

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
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
