Secretion of [³⁵S]-amino acid labelled MUC2. [³⁵S]-amino acid labelled homogenates were analysed on reducing SDS-PAGE, and the MUC2 band was quantified. The secreted percentage of MUC2 was calculated per biopsy specimen. Average values were calculated per patient from the duplicate values of the specimens, and the mean values per patient group were determined. Each point represents the average value of one patient. Mean (SEM) values per patient group: controls (22.17 (2.55)%), active ulcerative colitis (UC) (23.08 (2.55)%) and ulcerative colitis in remission (23.47 (4.16)%). Horizontal bars denote the mean of each patient group.
