Infliximab antibody | AbD20436_hIgG1
A microtiter plate was coated over night with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using HRP-conjugated Human Anti-Infliximab Antibody (clone AbD20436_hIgG1) at a concentration of 2 μg/ml followed by QuantaBlu Fluorogenic Peroxidase Substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit.
A microtiter plate was coated over night with Human IgG1/kappa, Human IgG1/lambda, cetuximab or infliximab at a concentration of 5 µg/ml. After washing with PBST and blocking with PBST+5% BSA, detection was performed using HRP-conjugated Human Anti-Infliximab Antibody (clone AbD20436_hIgG1) titrated to the given concentrations in PBST, followed by QuantaBlu Fluorogenic Peroxidase Substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit.
A microtiter plate was coated over night with Human Anti-Infliximab (clone AbD20436, HCA234) at a concentration of 0.6 µg/ml. After washing and blocking with PBST+5% BSA, 10% Human serum was added spiked with increasing concentrations of infliximab. Detection was performed using HRP-conjugated Human Anti-Infliximab (clone AbD20436_hIgG1) at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit.
A microtitre plate was coated over night with infliximab 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 Human Anti-Infliximab (clone AbD20436_hIgG1). Detection was performed using HRP-conjugated infliximab at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049) and QuantaBlu Fluorogenic Peroxidase Substrate. HRP-conjugation of infliximab used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit.
Human anti Infliximab
Anti-infliximab antibody is a recombinant, neutralizing, high affinity anti-idiotypic antibody in full IgG1 format, ideal for bioanalytical assays for infliximab and biosimilars. It can be used as the detection antibody in a PK bridging ELISA and as a reference standard in an ADA bridging ELISA.

Human Anti-Infliximab Antibody, clone AbD20436_hIgG1, is an affinity matured anti-idiotypic antibody that specifically recognizes free infliximab but not infliximab 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.
This antibody inhibits the binding of infliximab to TNFα and can be used as a detection antibody in a pharmacokinetic (PK) bridging ELISA to measure free drug. 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 IgG1 kappa monoclonal antibody approved for the treatment of psoriasis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis and ulcerative colitis. This therapeutic antibody is directed against TNFα and acts by blocking the binding of TNFα to its receptors, resulting in a down-regulation of the inflammatory response associated with autoimmune diseases.
