Human anti etanercept specificity ELISA

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 HRP conjugated Human anti etanercept (clone AbD26183_hIgG1, HCA279P) at a concentration of 2 μg/ml in HISPEC diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate

Human anti etanercept specificity titration ELISA

A microtiter plate was coated overnight with etanercept, TNFR2, Fc control or infliximab at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using HRP conjugated human anti etanercept (clone AbD26183_hIgG1) titrated to the given concentrations in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data for binding to etanercept and TNFR2 are shown as the mean of three measurements

Etanercept bridging ELISA for pharmacokinetic (PK) assay development

A microtiter plate was coated overnight with Human anti etanercept (clone AbD25939, HCA276) at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of etanercept. Detection was performed using HRP conjugated Human anti etanercept (clone AbD26183_hIgG1) at a concentration of 2 μg/ml in HISPEC assay diluent (BUF049A) and 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®

Human anti etanercept inhibition ELISA

A microtiter plate was coated overnight with human TNFα at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, a pre-incubated mixture of etanercept (0.3 μg/ml) plus increasing concentrations of Human anti etanercept (clone AbD25940_hIgG4Pro, HCA277, or clone AbD26183_hIgG1, HCA279) in the monovalent Fab format was added. Free etanercept, still capable of binding to the human TNFα coated plate, was detected using Mouse anti Human IgG (Fc) CH2 Domain:HRP antibody (MCA647P) and QuantaBlu™ fluorogenic peroxidase substrate.Data are shown as the mean of three measurements

(Rated 0.0 out of 5 based on 0 customer reviews)
    Anti-Etanercept Antibody recognizes etanercept at the region of the fusion of p75 (TNFR2) with the Fc portion of human IgG1. It binds to both free etanercept and to etanercept bound to TNF alpha, and may be used as a detection antibody in a bridging ELISA to measure total etanercept very specifically.

      • Human anti etanercept, clone AbD26183_hIgG1 is an antibody that specifically recognizes etanercept at the region of the fusion of p75 with the Fc portion of human IgG1. The antibody does not inhibit the binding of etanercept to its target tumor necrosis factor alpha (TNFα); it binds to both free etanercept and to etanercept bound to its target TNFα and can be used to measure total etanercept very specifically.

        The antibody can be used to develop a pharmacokinetic (PK) bridging assay to measure total drug in patient samples. This antibody, in full immunoglobulin format, is recommended as the detection antibody, paired with the antibody clone AbD25939 (HCA276) in monovalent Fab format, as the capture antibody.

        Etanercept (Enbrel®) is a dimeric fusion protein consisting of the extracellular ligand-binding portion of the human 75 kDa (p75) TNFR2 linked to the Fc portion of human IgG1. The Fc component of etanercept contains the CH2 domain, the CH3 domain and hinge region, but not the CH1 domain of IgG1. It is used to treat autoimmune diseases by interfering with TNF, acting as a TNF inhibitor. It binds to both TNFα and TNFβ (Lymphotoxin A).
