Proteomics Dynamic Range Standard Set, Protein Mass Spectrometry Calibration Standard

Storage: -20C

EC Number: 232-650-8

UNSPSC Code: 12352200

General description: The Proteomics Dynamic Range Standard Set is produced from a mixture of 48 individual human source or human sequence recombinant proteins, each of which has been selected to limit heterogeneous post-translational modifications (PTMs). The protein standard is formulated from 6 mixtures of 8 proteins to present a dynamic range of 5 orders of magnitude, ranging from 50 pmoles to 500 amoles. Each protein has been quantitated by amino acid analysis (AAA) prior to formulation.

Application: The Proteomics Dynamic Range Standard Set can be used to standardize and/or evaluate mass spectrometric (e.g., LC-MS/MS, MALDI-TOF-MS, etc.) and electrophoretic analysis conditions prior to the analysis of complex protein samples. UPS2 can be used to bracket precious experimental data sets between runs of a known complex standard sample. This allows confirmation of the robustness of the analysis method and stability of the instrument employed. Additionally, laboratories generating or comparing mass spectrometric data derived from poorly defined samples can use UPS2 as an external reference to assist with the evaluation of results and experimental methodology.Proteomics Dynamic Range Standard Set has been used for the quantification of dynamic range universal protein standard on Orbitrap Analyzer using all ion fragmentation. It has been used as a standard for intensity-based absolute quantification of proteins (iBAQ) in LC-MS (liquid chromatography-mass spectrometry)/MS analysis.
