Palivizumab antibody | AbD23967
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 human anti palivizumab (clone AbD23967) at a concentration of 2 μg/ml followed by an HRP labeled anti-DYKDDDDK tag antibody in HISPEC diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate
A microtiter plate was coated over night with palivizumab, human IgG1/kappa, human IgG1/lambda, natalizumab, trastuzumab or tocilizumab at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using human anti palivizumab (clone AbD23967) titrated to the given concentrations in PBST, followed by an HRP labeled anti-His tag antibody 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) 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
Anti-palivizumab antibody is a recombinant, neutralizing, anti-idiotypic antibody in monovalent Fab format; it is ideal for bioanalytical assays to measure levels of palivizumab and biosimilars. It is suitable as capture and detection antibody in a PK bridging ELISA format.

Human anti Palivizumab, clone AbD23967, 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.
Our anti palivizumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as the capture antibody, paired with the antibody in full immunoglobulin (Ig) format, clone AbD23967_hIgG1 (HCA262), as the detection antibody. The antibody in Ig format can also be used to develop and calibrate immune response assays to measure the anti-drug antibody (ADA) response in patient sera.
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.
