Immobilized Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290) at 5 μg/mL, add Trastuzumab Deruxtecan in the 100% Human Serum and then add Biotinylated Human Her2, His,Avitag, premium grade (Cat. No. HE2-H82E2) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (QC tested).
Protocol
Immobilized Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290) at 5 μg/mL, add Trastuzumab Deruxtecan in the 0.5% BSA and then add Biotinylated Human Her2, His,Avitag, premium grade (Cat. No. HE2-H82E2) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (Routinely tested).
Protocol
Serial dilutions of DXD were added into Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290): Trastuzumab Deruxtecan binding reactions. The half maximal inhibitory concentration (IC50) is 0.05452 μg/mL (Routinely tested).
Protocol
Cross Verification

ELISA binding of Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290) with Disitamab Vedotin (RC48), Trastuzumab Deruxtecan, Sacituzumab Govitecam, Trastuzumab MMAE, Doxorubicin-ADC and IgG1-MMAF conjugated antibody respectively.
The coating antibody was Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290), used at 1 μg/mL concentration. The primary antibody were different payload conjugated antibodies, including Disitamab Vedotin (RC48), Trastuzumab Deruxtecan, Sacituzumab Govitecam, Trastuzumab MMAE, Doxorubicin-ADC and IgG1-MMAF conjugated antibodies used at 0.5 μg/mL concentration. The secondary antibody was HRP conjugated Anti-Human-IgG-Fc Antibody (6F11C8), mAb (Acro, Cat. No. IGG-LY69) used at 1:10000 concentration.
Monoclonal Anti-DXD & Exatecan Antibody, Rabbit IgG (M1B09) (Cat. No. DXD-MY2290) is specific to Trastuzumab Deruxtecan, and has no cross-reactivity with Disitamab Vedotin (RC48), Sacituzumab Govitecam, Trastuzumab MMAE, Doxorubicin-ADC and IgG1-MMAF (Routinely tested).
