Protein sample preparation for mass spectrometry analysis, MALDI-TOF, includes (sometimes) ______.
I. protein labeling
II. protein sequencing
III. mixing with a matrix
IV. protein migration
V. protein separation

Question

Quizplus · Accepted Answer

Protein sample preparation for MALDI-TOF mass spectrometry often includes protein labeling to facilitate detection, mixing with a matrix to assist in ionization, and protein separation to resolve complex mixtures before analysis. Protein sequencing is not a preparation step but rather an outcome of the analysis, and protein migration refers to techniques like electrophoresis, which might be used in preparation but is not specific or necessary for MALDI-TOF.
