Application Abreviews Notes
Sandwich ELISA Use a concentration of 0.5 µg/ml. Can be paired for Sandwich ELISA with Mouse monoclonal [MEM-226] to CD105 (ab2529). For sandwich ELISA, use this antibody as Detection at 0.5 µg/ml with Mouse monoclonal [MEM-226] to CD105 (ab2529) as Capture.
ELISA Use a concentration of 1 - 15 µg/ml.
WB Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 71 kDa.
Flow Cyt Use at an assay dependent concentration. ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.


  • FunctionMajor glycoprotein of vascular endothelium. May play a critical role in the binding of endothelial cells to integrins and/or other RGD receptors.
  • Tissue specificityEndoglin is restricted to endothelial cells in all tissues except bone marrow.
  • Involvement in diseaseDefects in ENG are the cause of hereditary hemorrhagic telangiectasia type 1 (HHT1) [MIM:187300, 108010]; also known as Osler-Rendu-Weber syndrome 1 (ORW1). HHT1 is an autosomal dominant multisystemic vascular dysplasia, characterized by recurrent epistaxis, muco-cutaneous telangiectases, gastro-intestinal hemorrhage, and pulmonary (PAVM), cerebral (CAVM) and hepatic arteriovenous malformations; all secondary manifestations of the underlying vascular dysplasia. Although the first symptom of HHT1 in children is generally nose bleed, there is an important clinical heterogeneity.
