DigesTip is a new device for in-solution protein digestion, based on a patent pending technology, able to immobilize enzymes (trypsin, in this case) on a solid surface, keeping their activity preserved. DigesTip is a standard pipette tip, usable both by human and by robots. Its main performances are: very short digestion time (1 min) and usability with low protein sample concentrations (5 g/mL). DigesTip obtains a clear signal in MS measurements and its usage rules out several preparative steps.
