Delta-like protein 4/DLL4 Protein, Human (HEK293, Fc)

Cat. No.: HY-P75294
COA Handling Instructions

The DLL4 protein, a homolog of the Drosophila delta gene family, encodes Notch ligands with a DSL domain, EGF repeats, and a transmembrane domain. DLL4 is widely expressed in tissues, including placenta (RPKM 11.5), fat (RPKM 11.2), and 22 others. Delta-like protein 4/DLL4 Protein, Human (HEK293, Fc) is the recombinant human-derived Delta-like protein 4/DLL4 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of Delta-like protein 4/DLL4 Protein, Human (HEK293, Fc) is 498 a.a., with molecular weight of 100-110 kDa.

Background

Delta-like protein 4 (DLL4) is a homolog of the Drosophila delta gene family, encoding Notch ligands that possess a DSL domain, EGF repeats, and a transmembrane domain. DLL4 displays broad expression in various tissues, including placenta (RPKM 11.5), fat (RPKM 11.2), and 22 other tissues.

Biological Activity

1. Measured by the ability of the immobilized protein to enhance BMP2-induced alkaline phosphatase activity in C3H10T1/2 mouse embryonic fibroblast cells and the ED50 is typically 2.2 µg/mL in the presence of 500 ng/mL recombinant human BMP2.
2. Measured by the ability of the immobilized protein to enhance BMP-2 induced alkaline phosphatase activity in C3H10T1/2 mouse embryonic fibroblast cells. The ED50 for this effect is approximately 0.05348 μg/ml in the presence of 100 ng/mL Mouse BMP-2, corresponding to a specific activity is 1.870×10^4 units/mg.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 (Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. ) or 20 mM PB, 150 mM NaCl, pH 7.4.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
