MALDI plates with proteolytic enzymes

A/The mass spectrum of peptides from human haptoglobin incubated for 2 hours on the trypsin MALDI chip at 37 °C. The detected peptides cover 46% of the total sequence.
B/ The mass spectrum of peptides from myoglobin incubated for 20 minutes on the trypsin MALCI chip surface at 37 °C. The detected peptides cover 78% of the total sequence.
