Infliximab antibody | AbD19370_hIgG1
To confirm antibody specificity, a microtiter plate was coated overnight with various antigens at a concentration of 5μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using HRP-conjugated HCA215 at 2μg/ml, followed by QuantaBlu fluorogenic peroxidase substrate.
A microtiter plate was coated overnight with HCA215 (as Fab fragment) at 5.0 μg/mL. After washing and blocking with PBST+5% BSA, Infliximab alone (red circles), or with 5.0 fold molar excess of TNF-α (black squares) was added in the given concentrations. Free or TNF-α bound Infliximab binding to HCA215 was detected using Mouse anti Human IgG (Fc) CH2 domain:HRP (MCA647P).
A microtiter plate was coated overnight with HCA212 at a concentration of 5µg/ml. After washing and blocking with PBST+5% BSA, Infliximab spiked in 10% human serum was added at the given concentrations. Detection was performed using HRP-conjugated HCA215 at 2μg/ml in HISPEC assay diluent (BUF049), and QuantaBlu fluorogenic peroxidase substrate.
A microtiter plate was coated overnight with Infliximab at a concentration of 1μg/ml. After washing and blocking with PBST+5% BSA, anti Infliximab HCA215 spiked in 10% human serum was added at the given concentrations. Detection was performed using HRP-conjugated Infliximab.

Antibody Quality and Performance Guarantee
| Human anti Infliximab, clone AbD19370_hIgG1, is an anti-idiotypic antibody that specifically recognizes free infliximab monoclonal antibody and infliximab when bound to its target, Tumor Necrosis Factor Alpha (TNFα). It can be used in bioanalytical assays to measure the levels of infliximab and biosimilar products, such as Inflectra and Renflexis, in patient samples. Human anti Infliximab, clone AbD19370_hIgG1 is not paratope-specific and is non-inhibitory; it binds to an epitope outside the infliximab binding site. This epitope is shared with other chimeric antibodies that are highly homologous to infliximab including the chimeric antibody cetuximab, but not rituximab. The antibody can be used as a detection antibody in a pharmacokinetic (PK) assay in the bridging format to measure total drug (free, partially bound and fully bound). As it is a fully human antibody, it can also be used to develop and calibrate immune response assays to measure the anti-drug antibody (ADA) response in patient sera. Infliximab (branded as Remicade®) is a chimeric monoclonal antibody drug (IgG1/kappa) that has been approved for treatment of psoriasis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis, and ulcerative colitis. It is directed against TNFα and acts by blocking the binding of this cytokine to its receptors. Infliximab also induces apoptosis of TNFα expressing T-lymphocytes.
