Trypsins In Human Pancreatic Juice–Their Distribution as Found in 34 Specimens. Two Human Pancreatic Trypsinogens

Trypsinogen I was found in 33 of 34 patient pancreatic juice specimens and trypsinogen II was found in 11 patients. Trypsinogen I was found in ten of the latter patients. The trypsinogen 1 band represented 13.4 ± 11.5 per cent of the total protein found in the juice, while trypsinogen II represented 1.4 ± 3.4 per cent. The isoelectric point of trypsinogen I was 7.0 and that of trypsinogen II was 4.7–5.0.
