Application Abreviews Notes
ICC/IF Use at an assay dependent concentration.
IHC-P 1/100.

  • Function
    Ligand for multiple Notch receptors and involved in the mediation of Notch signaling. May be involved in cell-fate decisions during hematopoiesis. Seems to be involved in early and late stages of mammalian cardiovascular development. Inhibits myoblast differentiation (By similarity). Enhances fibroblast growth factor-induced angiogenesis (in vitro).
  • Tissue specificity
    Widely expressed in adult and fetal tissues. In cervix epithelium expressed in undifferentiated subcolumnar reserve cells and squamous metaplasia. Expression is up-regulated in cervical squamous cell carcinoma. Expressed in bone marrow cell line HS-27a which supports the long-term maintenance of immature progenitor cells.
  • Involvement in disease
    Defects in JAG1 are the cause of Alagille syndrome type 1 (ALGS1) [MIM:118450]. Alagille syndrome is an autosomal dominant multisystem disorder defined clinically by hepatic bile duct paucity and cholestasis in association with cardiac, skeletal, and ophthalmologic manifestations. There are characteristic facial features and less frequent clinical involvement of the renal and vascular systems.
    Defects in JAG1 are a cause of tetralogy of Fallot (TOF) [MIM:187500]. TOF is a congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. This condition results in a blue baby at birth due to inadequate oxygenation. Surgical correction is emergent.
  • Sequence similarities
    Contains 1 DSL domain.
    Contains 15 EGF-like domains.
  • Developmental stage
    Expressed in 32-52 days embryos in the distal cardiac outflow tract and pulmonary artery, major arteries, portal vein, optic vesicle, otocyst, branchial arches, metanephros, pancreas, mesocardium, around the major bronchial branches, and in the neural tube.

  • Formalin-fixed paraffin embedded IHC of normal human cervial tissues (40x magnification) stained with ab7771 (1/100 dilution). The slides were counterstained with hematoxylin

  • Staining of Human corneal epithelial cells with anti-Jagged1 (ab7771, 1/500). The Jagged1 (green staining) is localised to the cytoplasm and cell nucleus and is consistent with reports in the literature. The nucleus is stained with Bis benzimide (1/500, blue staining).
