CSC-CTK0599
Description
Human sDLL-1 comprises the extracellular signaling domain of DLL1, 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.
Species

Product Overview
Human DLK1 expressed in 293T cells
Molecular Mass
N/A
Size
CAT# CSC-CTK0599-25 (25 μg); CAT# CSC-CTK0599-125 (125 μg)
Expression System
293T cells
Purity
Greater than 95% as determined by SDS-PAGE and RP-HPLC analysis.
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.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Sterile-filtered through a 0.2 micron filter. Lyophilized from a protein solution in 1X PBS (pH 7.5).
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultrapure water or aqueous buffers to a concentration of 0.1- 1.0 mg mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
