Ustekinumab antibody | AbD17829
Antigens were coated at 5 μg/mL on a microtiter plate overnight. After washing and blocking with 5% BSA, the anti-Ustekinumab antibody, clone AbD17829 (20μL from a 2μg/mL solution) was added followed by Mouse anti-V5-tag:HRP (MCA1360P) in HiSPEC buffer (BUF049). Detection was performed using a fluorogenic peroxidase substrate.
IL-23 (1.0 μg/mL) was used as the coating antigen followed by a pre-incubated mixture of the anti-idiotypic antibody (HCA208) titrated into a constant amount of Ustekinumab (0.3 µg/mL). Free Ustekinumab still capable of binding to the plate was detected using Mouse anti Human IgG(Fc):HRP (MCA647P). Data is shown as the mean of three measurements.
Anti-Ustekinumab antibody HCA208 (AbD17829) was coated at 1.0 μg/mL on a microtiter plate overnight. After washing and blocking with 5% BSA in PBST, Ustekinumab spiked into 10% human serum was added. Detection was performed by adding HRP conjugated anti-Ustekinumab antibody HCA210, 2 μg/mL in HiSPEC buffer (BUF049), plus a fluorogenic peroxidase substrate. Data is shown as the mean of three measurements.

Antibody Quality and Performance Guarantee
| Human Anti-Ustekinumab Antibody, clone AbD17829 is a paratope specific, anti-idiotypic antibody that specifically recognizes the monoclonal antibody drug ustekinumab and inhibits binding to its target. The antibody can be used to measure the level of free ustekinumab and biosimilar products in bioanalytical and patient monitoring assays. A pair of anti-ustekinumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as a capture antibody, paired with an HRP conjugated Anti-Ustekinumab Antibody in full immunoglobulin format, clone AbD17827_hIgG1 (HCA210) as the detection antibody. Ustekinumab (Stelara) is a fully human monoclonal antibody drug (IgG1/kappa) that has been approved in US, Canada, and Europe for the treatment of plaque psoriasis and psoriatic arthritis. The FDA approved the medication for the treatment of moderate-severe Crohn's disease in 2016. The drug blocks interleukin IL-12 and IL-23 by binding with high affinity and specificity to the p40 subunit, preventing the binding of these two cytokines to T-lymphocytes, and thereby disrupting the proinflammatory pathway.
