Development and Application of a quantitative Mass spectrometry based Platform for Thermodynamic Analysis of Protein interaction Networks
… at a systems level. Current approaches for the analysis of protein -protein interactions are generally not quantitative and largely limited to certain types of interactions such as binary and strong binding interactions. They also have high false-positive and false-negative rates. Described here …
