Customer Review

Based on 1 publication(s) in Google Scholar

Jagged-1/JAG1 protein is a ligand for multiple Notch receptors and crucially mediates Notch signaling through interactions with NOTCH1, NOTCH2, and NOTCH3. Its role in hematopoiesis suggests its involvement in the regulation of blood cell development. Jagged-1/JAG1 Protein, Human (HEK293, Fc) is the recombinant human-derived Jagged-1/JAG1 protein, expressed by HEK293 , with C-hFc labeled tag.

Description

Jagged-1/JAG1 protein is a ligand for multiple Notch receptors and crucially mediates Notch signaling through interactions with NOTCH1, NOTCH2, and NOTCH3. Its role in hematopoiesis suggests its involvement in the regulation of blood cell development. Jagged-1/JAG1 Protein, Human (HEK293, Fc) is the recombinant human-derived Jagged-1/JAG1 protein, expressed by HEK293 , with C-hFc labeled tag.

Background

The Jagged-1 (JAG1) protein functions as a ligand for multiple Notch receptors, playing a crucial role in mediating Notch signaling, as evidenced by its interactions with NOTCH1, NOTCH2, and NOTCH3. Its involvement in cell-fate decisions during hematopoiesis suggests a regulatory role in blood cell development. JAG1 is implicated in various stages of mammalian cardiovascular development and has been associated with both early and late phases of this process. Additionally, it inhibits myoblast differentiation and enhances fibroblast growth factor-induced angiogenesis in vitro. Notably, the interaction between JAG1 and NOTCH1 is calcium ion-dependent, highlighting the complexity of its regulatory mechanisms in cellular processes.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.
