    Anti-MAdCAM1 antibody [314G8]
    See all MAdCAM1 primary antibodies
  • Description

    Mouse monoclonal [314G8] to MAdCAM1
  • Host species

  • Tested applications

    Suitable for: Flow Cyt, IHC-P, ELISA, WB, Functional Studies, IHC-Frmore details
  • Species reactivity

    Reacts with: Human
  • Immunogen

    Recombinant soluble MAdCAM-1-fc fusion protein (Human).

  • General notes

    Clone 314G8 reacts with the ligand binding first Ig domain and reports suggest that a splice variant exists in the gut which is not recognised by clone 314G8. Clone 314G8 is reported to block the interaction of MAdCAM1 with alpha 4 beta 7 (see reference 1).



Our Abpromise guarantee covers the use of ab34247 in the following tested applications.

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

  • Function

    Cell adhesion leukocyte receptor expressed by mucosal venules, helps to direct lymphocyte traffic into mucosal tissues including the Peyer patches and the intestinal lamina propria. It can bind both integrin alpha-4/beta-7 and L-selectin, regulating both the passage and retention of leukocytes. Isoform 2, lacking the mucin-like domain, may be specialized in supporting integrin alpha-4/beta-7-dependent adhesion strengthening, independent of L-selectin binding.
  • Tissue specificity

    Highly expressed on high endothelial venules (HEV) and lamina propia venules found in the small intestine, and to a lesser extent in the colon and spleen. Very low levels of expression found in pancreas and brain. Not expressed in the thymus, prostate, ovaries, testis, heart, placenta, lung, liver, skeletal muscle, kidney or peripheral blood leukocytes.
  • Sequence similarities

    Contains 2 Ig-like (immunoglobulin-like) domains.
  • Post-translational

    The Ser/Thr-rich mucin-like domain may provide possible sites for O-glycosylation.
  • Cellular localization
