일반 설명

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.

애플리케이션

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.

If proteome datasets are to be collated, shared, and merged for higher level proteome analyses, there is a need for generally accepted strategies and reagents for optimization and standardization of instrument performance. At present, there is no single protein or

An important area of proteomics involves the need for quantification, whether relative or absolute. Many methods now exist for relative quantification, but to support biomarker proteomics and systems biology, absolute quantification rather than relative quantification is required. Absolute quantification usually
