Denosumab antibody | AbD26862_hIgG1
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-Denosumab Antibody (clone AbD26862_hIgG1, HCA282) 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 microtiter plate was coated overnight with denosumab, human IgG2/kappa or human IgG1/lambda at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed Human Anti-Denosumab Antibody (clone AbD26862, here as his-tagged monovalent Fab fragment) titrated to the given concentrations in PBST, followed by detection with Mouse Anti-Penta Histidine Tag:HRP (MCA5995P) and QuantaBlu Fluorogenic Peroxidase Substrate. Data is shown as the mean of three measurements.
A microtiter plate was coated overnight with denosumab 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-Denosumab Antibodies, clone AbD26295_hIgG1 (HCA280, black line; KD = 1.8 nM), clone AbD26296_hIgG1 (HCA281, red line; KD = 7.1 nM) or clone AbD26862_hIgG1, HCA282 (blue line; KD = 0.8 nM). Detection was performed using HRP conjugated denosumab followed by QuantaBlu Fluorogenic Peroxidase Substrate. HRP conjugation of the denosumab used in this assay was performed using a LYNX Rapid HRP Conjugation Kit®. Data is shown as the mean of three measurements.
A microtiter plate was coated overnight with recombinant human RANKL at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, denosumab was added (0.3 μg/ml), spiked with increasing concentrations of each of three Human Anti-Denosumab Antibodies, clone AbD26295_hIgG1 (HCA280), and AbD26862_hIgG (HCA282), both in monovalent Fab format in this assay, and clone AbD26296 (HCA288). Detection of denosumab was performed using Mouse Anti-Human IgG (Fc) CH2 Domain:HRP Antibody (MCA647P) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data is shown as the mean of three measurements.

Antibody Quality and 
Unrivaled 
| Human Anti-Denosumab Antibody, clone AbD26862_hIgG1 is a paratope specific anti-idiotypic antibody that specifically recognizes the free human monoclonal antibody denosumab. The antibody does not recognize free RANKL (receptor activator of nuclear factor kappa-B ligand) or denosumab in complex with human RANKL and can be used to measure free denosumab and biosimilar products in bioanalytical assays. Clone AbD26862_hIgG1 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a reference standard in an anti-drug antibody (ADA) assay. Denosumab (Prolia, Xgeva) is a fully human monoclonal antibody (IgG2/kappa) for the treatment of osteoporosis, treatment-induced bone loss, bone metastases, multiple myeloma, and giant cell tumor of bone. The drug specifically binds to human RANKL a protein that acts as the primary signal to promote bone removal/resorption and prevents RANKL from activating its receptor, RANK, on the surface of osteoclasts and their precursors.
