Type 1 anti-secukinumab antibodies inhibit the binding of the monoclonal antibody drug secukinumab to its target, human interleukin 17A (IL-17A). They are ideal for development of a pharmacokinetic (PK) bridging ELISA to measure free drug. They are available in fully human IgG1 format, in three different affinities, for use as a surrogate positive control or reference standard for an anti-drug antibody (ADA) assay.
The Type 3 antibody specifically recognizes the drug-target complex, detecting secukinumab only when it is bound to IL17A. It is suitable as a detection antibody in a PK antigen capture assay, as an alternative assay format to the bridging ELISA.
