Fig. 1 MUC1 TR sequence showing 2 complete repeats and the positions of the TR epitopes detected by the antibodies LICRLonM8 and C595. Potential glycosylation sites are underlined.

Fig. 2 Examples of LICRLonM8 staining of antral biopsy specimens. Strong apical staining of surface epithelium, superficial glands, and mucus (biopsy specimen from a patient with normal histology). Perinuclear staining in the surface epithelium (biopsy specimen from a patient with H. pylori gastritis).

Fig. 3 Example of the very different pattern of staining of the TR antibody C595 and the cytoplasmic tail antibody F33. A and C are from an antral biopsy specimen from a patient with normal mucosa, and B and D show staining in a patient with normal H. pylori gastritis. A and B are stained with C595 and C and D with F33. Gastroenterology 2002 123, 41-49DOI: (10.1053/gast.2002.34157) Copyright © 2002 American Gastroenterological Association Terms and Conditions
Fig. 4 MUC1 allele length distribution. Histogram showing the distribution of allele lengths for each of the 3 groups (the data are shown as numbers of alleles; note that each individual has 2 alleles). Distribution of allele lengths, expressed as percentages, of the normal and H. pylori gastritis categories are compared with the larger set of Northern European individuals (n = 54 alleles, 27 people with normal histology; 46 alleles, 23 people with H. pylori gastritis; 446 alleles, 223 people, all other Northern European samples) Gastroenterology 2002 123, 41-49DOI: (10.1053/gast.2002.34157) Copyright © 2002 American Gastroenterological Association Terms and Conditions
Fig. 5 Comparison of MUC1 short and long alleles. Histogram showing the genotype of individuals in each group after recoding according to allele size. L, alleles 5.0 kilobases and longer; S, alleles shorter than 5.0 kilobases. Total number of alleles L and S in each of the 3 groups.
