Ranibizumab antibody | AbD29858_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-Ranibizumab Antibody, clone AbD29858_hIgG1 (HCA316P) at a concentration of 2 μg/ml in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate.
A microtiter plate was coated overnight with recombinant human VEGF-A (PHP293), ranibizumab or human Fab VH3-23/kappa1 at a concentration of 5 µg/ml. After washing and blocking with PBST+5% BSA, the human VEGF-A/ranibizumab complex was formed by adding 2 µg/ml ranibizumab to the wells coated with VEGF-A. Detection was performed using HRP conjugated Human Anti-Ranibizumab Antibody, clone AbD29858_hIgG1 (HCA316P) titrated to the given concentrations in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements.
A microtiter plate was coated overnight with recombinant human VEGF-A (PHP293) 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 ranibizumab. Detection was performed using HRP conjugated Human Anti-Ranibizumab Antibody, clone AbD29858_hIgG1 (HCA316P) at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate.

Human Anti-Ranibizumab Antibody, clone AbD29858_hIgG1 is a non-inhibitory, anti-idiotypic antibody in full immunoglobulin format that specifically recognizes the monoclonal antibody drug ranibizumab and ranibizumab when in complex with recombinant human vascular endothelial growth factor A (VEGF-A). It does not recognize free human VEGF-A or bevacizumab. This antibody can be used to measure levels of free ranibizumab and biosimilars in patient samples.
Clone AbD29858_hIgG1 in full immunoglobulin format can be used to develop a pharmacokinetic (PK) antigen capture format assay to measure free ranibizumab that has been captured via immobilized VEGF-A.
Ranibizumab (Lucentis) is a humanized Fab fragment antibody (VH3-23/kappa1), originating from the same parental mouse antibody as bevacizumab (Avastin); it has 4 amino acid exchanges in the heavy chain and 1 amino acid exchange in the light chain compared to bevacizumab. Ranibizumab was first approved to treat wet age-related macular degeneration (AMD), a common form of age-related vision loss. It is also approved for the treatment of macular edema following retinal vein occlusion, diabetic macular edema, and diabetic retinopathy. Ranibizumab inhibits angiogenesis by binding to VEGF-A, blocking its interaction with VEGF receptors on the surface of endothelial cells, and thus preventing the subsequent growth of new blood vessels.
