N-terminal Amino Acid Sequence Analysis

N-terminal Amino Acid Sequence Analysis by MALDI-TOF MS

N-terminal fragments can be isolated even from proteins with blocked N-terminals. N-terminal fragments from proteins with unblocked N-terminals can be recovered as sulfonic acid derivatives, which permitsde novosequencing by MALDI-MS/MS. N-terminal fragments can be separately isolated even if multiple proteins coexist in a single SDS-PAGE sample (band).

ORFinder-NB Mass Sequencing Kit (Protein N-Terminal Sequencing Kit)

  • Isolates N-terminal fragments from trypsin digests of proteins using DITC resins, whether the protein N-terminals are blocked or not.
  • Recovers N-terminal fragments from proteins with unblocked N-terminals as sulfonic acid derivatives. As a result, primarily y-sequence ions are detected in MS/MS spectra, enablingde novosequence analysis.
