Download our new white paper on QPrEST™+ - validated protein standards for targeted proteomics.

New white paper

Read our white paper "Validated Isotope-Labeled Protein Standard for Absolute Quantification Using Mass Spectrometry" for a detailed description of our QPrEST+ protein standards. The white paper covers: 

  • Validation according to the CPTAC assay criteria
  • Quantotypic peptides comparable to stable isotope-labeled full-length proteins
  • Linear responses for quantotypic peptides
  • Suitability for single-point calibration
