Top-down proteomics
Videos
Top-down proteomics is a method of protein identification capable of identifying and quantitating unique proteoforms through the analysis of intact proteins. The name is derived from the similar appro
Protein mass spectrometry
…ionization techniques are used in conjunction with mass analyzers such as tandem mass spectrometry. In general, the proteins are analyzed either in a "top-down" approach in which proteins are analyzed intact, or a "bottom-up" approach in which protein are first digested into fragments. An intermediate "middle-down…
