Need to observe all fragment ions? Like clarified spectra? More sensitivity? Higher sample throughput? Tryp-N™ can help!
Tryp-N™ is a thermophilic metalloprotease with N-terminal specificity for arginine and lysine developed at Cold Spring Harbor Laboratory (CSHL). By placing basic centers of peptides (the amino terminus and side chains of K/R) in one location, b-ions predominate in MS/MS.
