  • Source
    Biotinylated Human DLL3 Protein, His,Avitag, premium grade(DL3-H82E3) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Leu 492 (Accession # Q9NYJ7-1).
    Predicted N-terminus: His
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
  • Molecular Characterization
    DLL3 Structure

    This protein carries a polyhistidine tag at the N-terminus and an Avi tag (Avitag™) at the C-terminus.

    The protein has a calculated MW of 52.6 kDa. The protein migrates as 55-60 kDa under reducing (R) condition, and 48-53 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) 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 0.01 EU per μg by the LAL method.
  • Host Cell DNA
    <0.02 ng/μg of protein tested by qPCR.
  • Sterility
    The sterility testing was performed by membrane filtration method.
  • Mycoplasma
    Negative.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, 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.
