Recombinant Human DLL4 Protein (HEK293)，hFc

DLL4

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.

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. 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 0.05348μg/mL in the presence of 100 ng/mL Mouse BMP-2, corresponding to a specific activity is 1.870×104 units/mg.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
