Trastuzumab antibody | AbD16712
A microtiter plate was coated overnight with Human Anti-Trastuzumab, clone AbD16712 (HCA166) at a concentration of 1 μg/ml. After washing and blocking with PBST + 5% BSA, 10% human serum was added spiked with increasing concentrations of trastuzumab. Detection was performed using HRP conjugated Human Anti-Trastuzumab Antibody, clone AbD18018 (HCA168) at a concentration of 4 μg/ml in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements. HRP conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit (LNK002P).

A microtiter plate was coated overnight with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST + 5% BSA, detection was performed using Human Anti-Trastuzumab Antibody, clone AbD16712 (HCA166) at a concentration of 2 μg/ml followed by Mouse Anti-Strep-Tag Classic:HRP Antibody (MCA2489P) in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate.
Human anti Trastuzumab
Anti-trastuzumab antibody is a recombinant, neutralizing, high affinity anti-idiotypic antibody in monovalent Fab format; it is ideal for bioanalytical assays to measure levels of trastuzumab or biosimilars. It has been validated as capture and detection antibody in a PK bridging ELISA format.

Human anti Trastuzumab antibody, clone AbD16712 a monoclonal antibody recognizes 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.
Human anti Trastuzumab (AbD16712) is an anti-idiotypic antibody that specifically recognizes the Herceptin humanised monoclonal antibody and can be used to measure the Heceptin levels in serum from patients.
This clone has been demonstrated to inhibit the Herceptin - HER2 interaction. Removal of the preservative is recommended prior to use in functional assays.
