Product Overview
Recombinant human JAG1 (NP_000205.1) extracellular domain (Met 1-Ser 1046) was fused with Fc region of human IgG1 at the C-terminus.
Description
Protein Jagged 1, also known as JAG1, JAGL1, and CD339, is a single-pass type I membrane protein that contains 1 DSL domain and 15 EGF-like domains. JAG1/Jagged 1 is widely expressed in adult and fetal tissues. The expression of JAG1/Jagged 1 is up-regulated in cervical squamous cell carcinoma. JAG1/Jagged 1 is also expressed in bone marrow cell line HS-27a which supports the long-term maintenance of immature progenitor cells. JAG1/Jagged 1 is a ligand for multiple Notch receptors. It is involved in the mediation of Notch signaling. JAG1/Jagged 1 may be involved in cell-fate decisions during hematopoiesis. JAG1/Jagged 1 seems to be involved in the early and late stages of mammalian cardiovascular development. It inhibits myoblast differentiation and enhances fibroblast growth factor-induced angiogenesis. Defects in JAG1/Jagged 1 are the cause of Alagille syndrome type 1 (ALGS1). 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. Defects in JAG1/Jagged 1 are also a cause of tetralogy of Fallot (TOF). TOF is a congenital heart anomaly that 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.

Form
Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant human JAG1/Fc is a disulfide-linked homodimer. The reduced monomer consists of 1254 amino acids and has a predicted molecular mass of 137 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of human JAG1/Fc monomer is approximately 185.5 kDa due to glycosylation.
Protein length
Met1-Ser1046
Endotoxin
< 1.0 EU/μg of the protein as determined by the LAL method
Purity
> 85 % as determined by SDS-PAGE
Storage
Samples are stable for up to twelve months from date of receipt at -20 to -80 centigrade.
Store it under sterile conditions at -20 to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
Bioactivity-Cell based assay 1
Bioactivity-Cell based assay

Measured by the ability of the immobilized protein to enhance BMP2-induced alkaline phosphatase activity in C3H10T1/2 mouse embryonic fibroblast cells. The ED50 for this effect is typically 5-30 μg/mL.
