Gene Symbol: DLL-1
Accession #: O00548
Gene ID: 28514
Source: HEK 293 cells
Appearance: Lyophilized powder
Physical Form Description: Sterile filtered through a 0.2 micron filter. Lyophilized from 1X PBS, pH 7.5.
Molecular Weight: 57-60 kDa
Purity by SDS-PAGE: ≥95%
Purity by HPLC: N/A
Endotoxin Level: < 0.1 ng/μg of protein (<1EU/μg).
Biological Activity: Determined by the dose dependent growth suppression of the human acute monocytic leukemia cell line, THP-1. sDLL-1 inhibits the proliferation in THP-1 cells using a concentration of 3.0-5.0 μg/ml.
Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
Storage Temp.: -20°C
Shipping: Gel pack
Background Information: Human sDLL-1 comprises the extracellular signaling domain of DLL-1, a member of a structurally-related family of single-pass type I trans-membrane proteins that serve as ligands for Notch receptors. It is expressed in the heart and pancreas, and to a lesser extent in various other tissues. DLL-1 functions to specifically activate the Notch-1 and Notch-2 receptors. The Notch signaling pathway regulates endothelial-cell differentiation, proliferation and apoptosis, and is essential for the development, maintenance and remodeling of the vascular system. DLL-1 suppresses differentiation of hematopoietic progenitor cells into the B-cell lineage while promoting differentiation to T-cell and NK cell precursors. Recombinant human sDLL-1 is a 57.0-60.0 kDa glycoprotein containing 522 amino-acid residues.
