Protein elements assume a significant role in different capabilities. The intracellular climate essentially impacts protein elements, especially inherently scattered proteins (IDPs). An examination bunch drove Prof. Zhang Lihua from the Dalian Establishment of Compound Physical Science (DICP) of the Chinese Foundation of Sciences (CAS), as a team with Assoc. Prof. Gong Zhou from the Accuracy Estimation Science and Innovation Development Exploration Foundation of CAS, has proposed a technique involving in-vivo substance cross-connecting and mass spectrometry (in-vivo XL-MS) to disentangle the unique design of proteins inside cells. In-vivo XL-MS has potential for examining the powerful construction of proteins inside cells because
