Jump to Protein identification - There are two main ways MS is used to identify proteins. Peptide m. fingerprinting uses the of proteolytic peptides as input to a search of a database of predicted that would arise from digestion of a list of known proteins. If a protein sequence in the reference list gives . - During the past two decades, mspectrometry has become established as the primary method for protein identification from complex mixtures of biological origin. This is largely attributable to the fortunate coincidence of instrumental advances that allow routineysis of minute amounts typi.y .M. mapping, protein m. finger printing. A less complex method for identifying proteins relies on databases of protein sequences. After digesting a protein with trypsin or some other specific proteinase, the of the intact peptides are measured, usually with a MALDI instrument.. - In addition, the sequence of component amino acids can also be identified using the same procedure. Inyzing proteins using mspectrometry, the proteins are first broken down into their component peptides. Trypsin is usually the protease most researchers use in digesting proteins due to a number of reasons..
