Preparation and Storage
Stability and Storage
Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
FunctionLigand 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 specificityWidely 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 diseaseDefects 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 similaritiesContains 1 DSL domain.
Contains 15 EGF-like domains.
Developmental stageExpressed 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.
- Information by UniProt
Induction of Hes-1 with the treatment of recombinant Human Jagged1-Fc (ab108575).
A mouse preadpipocyte cell line, 3T3L1, was stimulated with 5μg/ml of ab108575 as in indicated time points and each cell lysate was prepared and subjected to western blot by using anti-mouse Hes1 or GAPDH.

NIH/3T3 cells were maintained in DMEM supplemented with 10% FBS and penicillin-streptomycin.
When the cells reached confluence, adipogenesis was initiated by adding IBMX, Dexamethasone, and insulin to 0.5mM, 1μM, and 10μg/ml, respectively and continued for 2 days (day 0).
The medium was replaced every 2 days with new medium containing insulin in the presence or absence of 5μg/ml of human Jagged1-Fc (ab108575) and human CD137-Fc as a control-Fc. Staining with Oil Red O was typically performed on day 7
