WebMay 10, 2016 · The effect of increasing the trypsin amount in bottom-up based targeted protein analysis is evaluated. By applying an increased trypsin-to-protein ratio (1:1 (w/w)) after heat denaturation (60 °C), reduction and alkylation, the digestion time could be reduced profoundly compared to conventional digestion conditions (ratio 1:40, overnight) without … WebFor Solution Digests – Prepare the trypsin in 1 mM HCl at a concentration of 1 mg/ml (20 µl of 1 mM HCl for a 20 µg vial). This results in a solution containing 1 mg/ml trypsin, pH 3.0. For In-gel Digests – Prepare a solution by adding 100 µl of 1 mM HCl to one 20 µg vial of trypsin. Mix the vial briefly to ensure the trypsin is dissolved.
