Product Introduction

Bioactivity

Bioactivity	Immobilized Human DLL4, No Tag at 0.5 μg/ml (100 μl/well) on the plate. Dose response curve for Anti-DLL4 Antibody, hFc Tag with the EC50 of 8.7 ng/ml determined by ELISA.
Description	DLL4 Protein, Human, Recombinant V2 is expressed in HEK293 Cells. The accession number is Q9NR61.
Species	Human
Expression System	HEK293 Cells
Tag	Tag Free
Accession Number	Q9NR61
Construction	Ser27-Pro524
Protein Purity	> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from 0.22 μm filtered solution in PBS, 200 mM Arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/mL. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Synonyms	δ-like 4 (Drosophila), δ-like 4, hδ2, hdelta2, delta-like 4 (Drosophila), Delta-like 4
Research Background	Delta-like protein 4 (DLL4) is a type I membrane protein belonging to the Delta/Serrate/Lag2 (DSL) family of Notch ligands. Activates NOTCH1 and NOTCH4. Involved in angiogenesis; negatively regulates endothelial cell proliferation and migration and angiogenic sprouting. Essential for retinal progenitor proliferation. Required for suppressing rod fates in late retinal progenitors as well as for proper generation of other retinal cell types (By similarity). During spinal cord neurogenesis, inhibits V2a interneuron fate.

Storage & Solubility Information

Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Storage	Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
