    DXD SDS-PAGE

    HRP conjugated Monoclonal Anti-DXD&Exatecan Antibody, Mouse IgG1 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).

  • 活性(Bioactivity)-ELISA

     DXD ELISA

    Immobilized Human Her2, His Tag (Cat. No. HE2-H5225) at 1 μg/mL, add Trastuzumab Deruxtecan in the 100% Human Serum and then add HRP conjugated Monoclonal Anti-DXD&Exatecan Antibody, Mouse IgG1 (Cat. No. DXD-PLM684) at 0.1 μg/mL (QC tested).

    Protocol
  •  DXD ELISA

    Immobilized Trastuzumab-Exatcan at 1 μg/mL (100 μL/well) can bind HRP conjugated Mouse Anti-DXD&Exatecan Antibody, Mouse IgG1 (Cat. No. DXD-PLM684) with a linear range of 1-16 ng/mL (Routinely tested).

    Protocol
  •  DXD ELISA

    Immobilized ADC-DXD at 1 μg/mL (100 μL/well) can bind HRP conjugated Mouse Anti-DXD&Exatecan Antibody, Mouse IgG1 (Cat. No. DXD-PLM684) with a linear range of 0.5-31 ng/mL (Routinely tested).

背景介绍

Dxd (Exatecan ADC derivative) is a potent DNA topoisomerase I inhibitor with an IC50 of 0.31 uM for targeting ADCs (DS-8201A). Dxd was cytotoxic to human tumor cell lines KPL-4, NCI-N87 and SK-BR, 3 and the IC50s of MDA-MB-468 was 1.43 NM-4.07 nM, while lgGADC (Dxd as payload) had no inhibitory effect on HER2 expression in the 4 cell lines. DS8201a (Dxd as payload) had a significant inhibitory effect on HER2-positive KPL-4 and NCI cell lines N87 and SK-BRwith IC50 values of 26.8, 25.4 and 6.7 ng/mL, respectively, but had no inhibitory effect on MDA MB-468 (IC50, > 10000 - mL). HRP-anti-DXD-antibody is a conjugation product of HRP and anti-DXD-antibody. It can be used in PK, PD analysis and ELISA.
