Each peptide is isolated in the mass spectrometer and characterized by tandem mass spectrometry (MS/MS or MS 2), which involves breaking the peptide into many smaller fragments and measuring the ...

Typically, if the threshold is not met, no assignment is made. Once a tandem mass spectrum is assigned a peptide sequence, the database(s) of known proteins is searched to define the antecedent ...

Advances in protein sequencing enable deeper insights and facilitate applications such as biomarker discovery and ...

Researchers from Humboldt University Berlin and HZB have developed a tandem solar cell combining a perovskite-based top cell with a CIGS (copper, indium, gallium, and selenium) bottom cell. By ...
