Ranibizumab antibody | AbD29928
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 Human Anti-Ranibizumab Antibody, clone AbD29928 (HCA304) at a concentration of 2 μg/ml and a rat anti-DYKDDDDK-tag antibody 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/ranibizumab complex was formed by adding 2 µg/ml ranibizumab to the wells coated with VEGF-A. Detection was performed using Human Anti-Ranibizumab Antibody, clone AbD29928 (HCA304) titrated to the given concentrations and a rat anti-DYKDDDDK-tag antibody 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 Human Anti-Ranibizumab Antibody, clone AbD29928 (HCA304) at a concentration of 2 µg/ml and a rat anti-DYKDDDDK-tag antibody in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate.

Antibody Quality and Performance Guarantee
| Human Anti-Ranibizumab Antibody, clone AbD29928 specifically recognizes the Fab fragment antibody drug ranibizumab when in complex with its target, human vascular endothelial growth factor A (VEGF-A). The antibody does not recognize free ranibizumab or unbound recombinant human VEGF-A. It can be used to measure levels of ranibizumab and biosimilars in patient samples. Clone AbD29928 is a monovalent Fab format antibody that can be used to develop a pharmacokinetic (PK) antigen capture assay to measure free ranibizumab captured via immobilized VEGF-A. This antibody also recognizes bevacizumab when in complex with human 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.
