As opposed to the colonic samples, no differences were observed between post-colitis and control animals with regard to trypsin-like activity (Boc-Gln-Ala-Arg-AMC: 381.46 (50.63–891.71) U/g versus 24.37 (5.90–547.00) U/g, p = NS, Tos-Gly-Pro-Arg-AMC: 571.95 (72.36–1687.43) U/g versus 65.04 (19.85–1073.75) U/g, p = NS, n = 16–20 per group, pooling of different treatment groups due to pre-treatment collection of fecal pellets, Figure 4A,B). The gene discussed is BOC; the disease is colitis.
