  • Synonym
    Delta3,delta-like 3 (Drosophila),delta-like protein 3,DLL3,Pudgy,SCDO1,SCDO1delta3
  • Source
    FITC-Labeled Human DLL3, His Tag(DL3-HF2H4) 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.

    The protein has a calculated MW of 50.4 kDa. The protein migrates as 50-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Conjugate

    FITC

    Excitation source: 488 nm spectral line, argon-ion laser

    Excitation Wavelength: 488 nm

    Emission Wavelength: 535 nm

  • Labeling
    The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular sieve treatment during purification process.
  • Protein Ratio
    The FITC to protein molar ratio is 1.5-3.5.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

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

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please protect from light and avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
DLL3 SDS-PAGE

FITC-Labeled Human DLL3, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).

Bioactivity-ELISA
 DLL3 ELISA

Immobilized Anti-DLL3 Antibody (specific Binding DSL of DLL3), Human IgG1 at 2 μg/mL (100 μL/well) can bind FITC-Labeled Human DLL3, His Tag (Cat. No. DL3-HF2H4) with a linear range of 0.01-0.313 μg/mL (QC tested).

  • 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.
