Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 540 kDa (predicted molecular weight: 540 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for ICC/IF or IP.
  • Target

    • Function

      Coats 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 specificity

      Colon, small intestine, colonic tumors, bronchus, cervix and gall bladder.
    • Sequence similarities

      Contains 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 localization

      Secreted. In the intestine, secreted into the inner and outer mucus layers.
