Deglycosylating the tissue is critical to expose epitope.


  • 功能Gel-forming mucin that is thought to contribute to the lubricating and viscoelastic properties of whole saliva and cervical mucus.
  • 组织特异性Expressed on surface airway epithelia. Expressed mainly in mucous cells of submucosal glands of airway tissues. Highly expressed in the sublingual gland. Also found in submaxillary glands, endocervix, gall bladder, and pancreas.
  • 序列相似性Contains 1 CTCK (C-terminal cystine knot-like) domain.
    Contains 3 HAT repeats.
    Contains 3 TIL (trypsin inhibitory-like) domains.
    Contains 3 VWFC domains.
    Contains 4 VWFD domains.
  • 结构域The cysteine residues in the Cys-rich subdomain repeats are not involved in disulfide bonding.
  • 翻译后修饰Highly glycosylated. C-, N- and O-glycosylated. C-mannosylated in the Cys-rich subdomains probably on the first Trp residue of the WXXW motif. Highly O-glycosylated in the Ser/Thr-rich tandem repeat (TR) region. The repeat region is about 59% O-glycosylated with a high abundance of NeuAc(2)Hex(1)HexNac1-ol.

  • ab77995 staining MUC5B in murine lung tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using citrate buffer pH 6.0. Samples were then incubated with the primary antibody at 2µg/ml for 16 hours at 4°C. MUC5B was revealed in black and nucleus are counterstain in blue (Fastblue).
  • ab77995 staining MUC5B in murine asthma lung tissue by Immunohistochemistry (Frozen sections). Tissue was fixed with formaldehyde, followed by incubation with the primary antibody at 4µg/ml for 16 hours at 4°C. ab77995 was coupled to biotin and Streptavidin 488 (1/250) was used to amplify the signal. Counterstained with DAPI (blue).
