Kit and method for identifying protein or peptide N-terminal amino acid

The present invention relates to a kit for identifying protein or peptide N-terminal amino acid and a method using the same. By using the formaldehyde-d2 (CD2O) and a reductant of the kit to identify the protein N-terminal amino acid, obvious a1 ions can be observed on an MS/MS. Further, the present...

More Information
Summary:The present invention relates to a kit for identifying protein or peptide N-terminal amino acid and a method using the same. By using the formaldehyde-d2 (CD2O) and a reductant of the kit to identify the protein N-terminal amino acid, obvious a1 ions can be observed on an MS/MS. Further, the present invention can also be used to identify whether a protein N-terminal modification is a chemical modification or an existing human body modification.
