Palivizumab antibody | AbD23967_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 palivizumab (clone AbD23967_hIgG1) at a concentration of 2 μg/ml in HISPEC diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate
A microtiter plate was coated over night with palivizumab, human IgG1/kappa or human IgG1/lambda at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using increasing concentrations of HRP conjugated human anti palivizumab (clone AbD23967_hIgG1) in HISPEC diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data for binding to palivizumab is presented as the mean of three measurements
A microtiter plate was coated over night with human anti palivizumab (clone AbD23967) 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 palivizumab. Detection was performed using HRP-conjugated human anti palivizumab (clone AbD23967_hIgG1) at a concentration of 2 μg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data is presented as the mean of three measurements
A microtiter plate was coated over night with human anti palivizumab (clone AbD23967_hIgG1) at a concentration of 0.5 μg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of palivizumab. Detection was performed using HRP-conjugated human anti palivizumab (clone AbD23967_hIgG1) at a concentration of 2 μg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data is presented as the mean of three measurements
A microtiter plate was coated over night with palivizumab at concentrations between 0.5 and 1.5 μg/ml. After washing and blocking with PBST+5% BSA, PBST with 10% human serum was added spiked with increasing concentrations of human anti palivizumab (clone AbD23967_hIgG1). Detection was performed using HRP conjugated palivizumab at a concentration of 2 μg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data is presented 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 Palivizumab:HRP
Anti-palivizumab antibody is a recombinant, neutralizing, anti-idiotypic antibody in fully human IgG1 format for bioanalytical assays to measure palivizumab 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 Palivizumab, clone AbD23967_hIgG1, is a paratope specific, high affinity, anti-idiotypic antibody that specifically recognizes the monoclonal antibody drug palivizumab and inhibits it binding to its target. The antibody can be used to measure the levels of palivizumab and biosimilar products in bioanalytical assays.
Clone AbD23967_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. Additionally the antibody can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody is recommended as the detection antibody and is available unlabeled or directly conjugated to HRP. Use in a pair with capture antibody clone AbD23967 (HCA261) in monovalent Fab format.
Palivizumab (Synagis®) is a humanized mouse monoclonal antibody (IgG1/kappa) specific to an epitope of the F protein of respiratory syncytial virus (RSV). It binds the antigenic site A, a highly conserved region on the RSV F protein between amino acids 258 and 275. RSV is known to cause infections of the lower respiratory tract in a clear seasonal pattern during the winter months. Administration of the drug is recommended for premature infants (under 35 weeks gestation), infants with certain congenital heart defects (CHD) or bronchopulmonary dysplasia (BPD) throughout the duration of the RSV season. It is approved by the FDA and EMA as a treatment for respiratory tract infection caused by RSV.
