    PAD-MY22121M1F9
  • Specificity

    Specifically recognizes PBD.

  • Source
    This panel contains Two anti-PBD monoclonal antibodies, suitable for pharmacokinetic (PK) detection of ADC with PBD as the payload. All the anti-PBD monoclonal antibodies are recombinantly expressed from HEK293, can be used as a capture antibody for detecting conjugated antibodies in ELISA assay.
  • Isotype
    Rabbit IgG | Rabbit Kappa
  • Purification

    Protein A purified / Protein G purified

  • Formulation

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

    Contact us for customized product form or formulation.

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
Bioactivity-ELISA
 PBD ELISA

Immobilized Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (M1D08) (Cat. No. PAD-MY2221) 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).

  • 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.
