Atlas Antibodies Presents QPrEST Standards for Absolute Quantification of Proteins using Mass Spectrometry
STOCKHOLM, Sweden, September 15, 2019. Atlas Antibodies AB, a leading supplier of advanced research reagents, announced today the introduction of pre-quantified QPrEST™ Protein Standards for absolute quantification of proteins in biological samples such as cell lysate and plasma using liquid chromatography (LC)–mass spectrometry (MS). QPrESTs consists of 50-150 amino acids identical to a part of the corresponding human protein. They are produced recombinantly in the presence of stable isotope-labeled (i.e. heavy) amino acids to generate protein standards. Targeted proteomics is a method
