  • General notes

    We have removed mouse from our list of reactive species based on contradictory results from researchers. We have had increased reports of negative staining results in IHC-P with mouse tissue. We do not batch test this antibody with mouse and we will no longer guarantee it for mouse reactivity.


    Storage in frost free freezers is not recommended. Should this product contain a precipitate we recommend microcentrifugation before use.



Our Abpromise guarantee covers the use of ab11197 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

WB Use at an assay dependent concentration. Predicted molecular weight: 621.5 kDa.


  • FunctionCoats the epithelia of the intestines, airways, and other mucus membrane-containing organs. Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. Major constituent of both the inner and outer mucus layers of the colon and may play a role in excluding bacteria from the inner mucus layer.
  • Tissue specificityColon, small intestine, colonic tumors, bronchus, cervix and gall bladder.
  • Sequence similaritiesContains 1 CTCK (C-terminal cystine knot-like) domain.
    Contains 1 TIL (trypsin inhibitory-like) domain.
    Contains 2 VWFC domains.
    Contains 4 VWFD domains.
  • Post-translational
    May undergo proteolytic cleavage in the outer mucus layer of the colon, contributing to the expanded volume and loose nature of this layer which allows for bacterial colonization in contrast to the inner mucus layer which is dense and devoid of bacteria.
    At low pH of 6 and under, undergoes autocatalytic cleavage in vitro in the N-terminal region of the fourth VWD domain. It is likely that this also occurs in vivo and is triggered by the low pH of the late secretory pathway.
  • Cellular localizationSecreted. In the intestine, secreted into the inner and outer mucus layers.

Thank you for contacting Abcam.
We have not specifically tested this antibody on immature and mature mucin. However, I have done some research. There's a paper which looks at O-glycosylation of MUC2. Specifically, this paper notices aberrant glyco...
