Fig. 6. MALDI-TOF analysis of insulin β-chain degradation by dentipain.

Fig. 6

One µl samples were added to 1 µl of matrix solution (saturated α-cyano-4-hydroxycinnamic acid in acetonitril/water mixture 7:3 v/v) and transferred onto a SCOUT MALDI plate. Analysis was performed using a MALDI-MS Reflex IV spectrometer equipped with a λ = 331 nm laser and an ion Time of Flight (TOF) analyzer.
