      • Trastuzumab, also known as Herceptin, is a drug used in the treatment of HER2 positive breast cancer and other HER2 overexpressing cancers including HER2-positive metastatic cancers of the gastrointestinal tract. Herceptin binds to the HER2 (or c-erbB2) proto-oncogene, an EGF receptor-like protein found on 20-30% of breast cancer cells. The binding leads to antibody mediated (complement mediated) killing of the HER2 positive cells.

        Clone AbD18141 is an anti-idiotypic antibody that specifically recognises the Herceptin humanised monoclonal antibody and can be used to measure the Heceptin levels in serum from patients.

        Clone AbD18141 has been demonstrated to inhibit the Herceptin - HER2 interaction. Removal of the preservative is recommended prior to use in functional assays - Bio-Rad recommend the use of a Slide-A-Lyser® dialysis cassette (EQU003) for this purpose.

        Additional Trastuzumab (Herceptin) specific anti-idiotypic antibodies are available upon request.
