Bioactivity-ELISA
 PBD ELISA

Immobilized Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) at 1 μg/mL, add Loncastuximab Tesirine in the 100% Human Serum and then add Biotinylated Human CD19 (20-291), His,Avitag, premium grade (Cat. No. CD9-H82E9) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (QC tested).

 PBD ELISA

Serial dilutions of (PBD)SG3199 were added into Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212)): Loncastuximab Tesirine binding reactions. The half maximal inhibitory concentration (IC50) is 0.02167 μg/mL (Routinely tested).

ELISA binding of Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) with Loncastuximab Tesirine, Disitamab Vedotin (RC48), IgG1-MMAF, Trastuzumab Deruxtecan, Sacituzumab Govitecam and Trastuzumab-DM1 conjugated antibody respectively.

The coating antibody was Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212), used at 1 μg/mL concentration. The primary antibody were different payload conjugated antibodies, including Loncastuximab Tesirine, Disitamab Vedotin (RC48), IgG1-MMAF, Trastuzumab Deruxtecan, Sacituzumab Govitecam and Trastuzumab-DM1 conjugated antibodies used at 0.25 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-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) is specific to Loncastuximab Tesirine and has no cross-reactivity with IgG1-MMAF, Disitamab Vedotin (RC48), Trastuzumab Deruxtecan, Sacituzumab Govitecam and Trastuzumab-DM1 (Routinely tested).

  • Background
    Pyrrolobenzodiazepine (PBD) dimer, is a new generation of cytotoxic payload used in antibody-drug conjugates (ADCs). The PBD dimer binds to the minor groove of DNA to form effective cytotoxic DNA interstrand crosslinks, which can block cell division and kill cancer cells. This mechanism of action utilizes a completely different cellular target from that of tubulin inhibitors, as well as a different DNA damage pattern from other DNA-targeting payloads. Anti-PBD antibody is a rabbit monoclonal antibody specially reacts with PBD, which is more sensitive than mouse antibody. The anti-PBD antibody is a useful reagent in PK assay to determine conjugated antibodies.
