Background: Imaging colonic mucus on living cells, tissues, and organs is required for live microscopy. Results: We have identified, synthesized, and validated a new human colonic mucus bacterial marker (MUB 70). Conclusion: This non-toxic marker is used to image the secreted colonic mucus. Significance: Beyond imaging applications, Cy5-MUB 70 might be used for diagnostic and prognosis applications on colonic mucinous carcinoma.
