    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic peptide corresponding to a region between residues 250 and 300 of human GPCR TGR5 (NP_733800.1).

Application Abreviews Notes
IHC-P 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF 1/50.
WB 1/1000 - 1/5000. Detects a band of approximately 33 kDa (predicted molecular weight: 35 kDa).

  • Function
    Receptor for bile acid. Bile acid-binding induces its internalization, activation of extracellular signal-regulated kinase and intracellular cAMP production. May be involved in the suppression of macrophage functions by bile acids.
  • Tissue specificity
    Ubiquitously expressed. Expressed at higher level in spleen and placenta. Expressed at lower level in other tissues. In digestive tissues, it is expressed in stomach, duodenum, ileocecum, ileum, jejunum, ascending colon, transverse colon, descending colon, cecum and liver, but not in esophagus and rectum.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization
    Cell membrane.

    Lanes 3-4 : Anti-GPCR TGR5 antibody (ab72608) at 1/5000 dilution

    Lane 1 : Pre-immune serum
    Lane 2 : Human spleen lysate
    Lane 3 : Mouse spleen lysate
    Lane 4 : Rat spleen lysate

    Predicted band size: 35 kDa
    Observed band size: 33 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 27 kDa. We are unsure as to the identity of these extra bands.

  • Formalin-fixed, paraffin-embedded mouse colon tissue stained for GPCR TGR5 with ab72608 at 1/200 dilution in immunohistochemical analysis. DAB staining. Counter stained with Hematoxylin.

  • HEK-293 (human epithelial cell line from embryonic kidney) cells stained for GPCR TGR5 (green) using ab72608 at 1/50 dilution ICC/IF.

    The nuclear counter stain is DAPI (blue). Alpha- tubulin is stained with Dylight 550 (red).

  • IHC image of ab72608 staining in human tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab72608, at 1/100 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Customer reviews and Q&As

We expect that glycosylation will apeear as a smear on the blot, rather than distinct bands, so I am skeptical that you are detecting TGR5. In addition, you should be seeing more signal in the membrane fraction, and not an identical banding pattern in ...
