C2-O-sLex was expressed in human primary colorectal adenocarcinomas.
| CHO-131 mAb staining reactivity in colorectal adenocarcinomas | ||||
|---|---|---|---|---|
| Differentiation status | 0+ | 1+ | 2+ | 3+ |
| Well differentiated | 1 | 10 (5) | 5 (4) | 6 (5) |
| Moderately differentiated | 13 | 10 (1) | 28 (12) | 32 (14) |

10 benign adenomas were negative for C2-O-sLex expression by CHO-131 staining. 28 normal tissues were negative for C2-O-sLex expression by CHO-131 staining. The brackets indicate the number of tissues where greater than 50% of the total tumor mass stained positively with CHO-131 mAb.
