  • Source
    Biotinylated Human DLL3, His,Avitag(DL3-H82E4) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Leu 492 (Accession # Q9NYJ7-1).
    Predicted N-terminus: Ala 27
  • Molecular Characterization
    DLL3 Structure

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 52.1 kDa. The protein migrates as 55-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4 with trehalose as protectant.

  • Background
    Delta-like protein 3 (DLL3) is a transmembrane protein that belongs to the Delta/Serrate/Lag-2 (DSL) family of Notch ligands.May be required to divert neurons along a specific differentiation pathway. Plays a role in the formation of somite boundaries during segmentation of the paraxial mesoderm. DLL3 protein is expressed on the surface of tumor cells but not in normal adult tissues.
