The recombinant protein fragments generated within the HPA program were used to develop a new concept for targeted proteomics based on stable isotope–labeled standards to allow for multiplex quantification of proteins in tissues and blood. This work was done in collaboration with Matthias Mann and coworkers at the Max Planck Institute of Biochemistry in Martinsried, Germany. This concept was later used by the HPA group to analyze the correlation of RNA and proteins in cells and tissues; and recently, multiplex assays for blood analysis have been developed to explore protein profiles in healthy and diseased individuals.
