Active Recombinant Human DLL4 protein, hFc-tagged

• Cat.No.: DLL4-0287H
• Product Overview: Recombinant Human DLL4 protein(NP_061947.1)(Met1-Pro524), fused with hFc tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: 1. Measured by its binding ability in a functional ELISA. Immobilized Mouse NOTCH1-His at 2 μg/ml (100 μl/well) can bind human DLL4-hFc, the EC50 of human DLL4-hFc is 15-90 ng/mL.2. Measured by the ability of the immobilized protein to enhance BMP2-induced alkaline phosphatase activity in C3H10T1/2 mouse embryonic fibroblast cells. The ED50 for this effect is typically 1-8 µg/mL in the presence of 500 ng/mL recombinant human BMP2.
• Molecular Mass: The recombinant human DLL4/Fc is a disulfide-linked homodimeric protein after removal of the signal peptide. The reduced monomer consists of 736 amino acids and predicts a molecular mass of 81 kDa. As a result of glycosylation, the rh DLL4/Fc monomer migrates as approximately 100-110 kDa band in SDS-PAGE under reducing conditions.
• Proteinlength: Met1-Pro524
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: ≥ 95 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
• Protein length: 1-524 a.a.
