Introducing QPrEST+ protein standards

QPrEST+ is an extension of our QPrEST™ product line for targeted proteomics

 

QPrEST+ are protein standards with a minimum of one peptide validated according to the CPTAC guidelines.QPrEST+ standards provide quantotypic peptides comparable to stable isotope-labeled full-length proteins. QPrEST+ standards show good linear responses over a large dynamic range, making them highly suitable for single-point calibration.

We currently offer nine off-the-shelf QPrEST+ standards targeting selected proteins, including LPA,  LRG1 and APOL1.
