Ustekinumab antibody | AbD17827_hIgG1
Antigens were coated at 5 μg/mL on a microtiter plate overnight. After washing and blocking with 5% milk powder in PBST, HRP-conjugated HCA210 (AbD17827_hIgG1; 20µL from a 2µg/mL solution in BUF049) was added. Detection was performed using the QuantaBlu™ 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 AbD17827 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.
A microtitre plate was coated over night with ustekinumab 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 Human anti ustekinumab (clone AbD17827_hIgG1). Detection was performed using HRP-conjugated ustekinumab at a concentration of 4 µg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data is shown as the mean of three measurements
Human anti Ustekinumab:HRP
Anti-ustekinumab antibody is a recombinant, high affinity anti-idiotypic antibody in full IgG1 format, ideal for bioanalytical assay development for ustekinumab and biosimilars. It is recommended as the detection antibody in PK bridging ELISA format with HCA208 or HCA209 as capture antibody.

Human Anti-Ustekinumab Antibody, clone AbD17827_hIgG1 is a paratope specific, high affinity, 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 levels of ustekinumab and biosimilar products in bioanalytical assays.
Clone AbD17827_hIgG1 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or calibrator in an anti-drug antibody (ADA) assay. Additionally it can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody is recommended as the detection antibody, paired with an anti-ustekinumab antibody in monovalent Fab format as the capture antibody, clone AbD17829 (HCA208) or clone AbD18334 (HCA209).
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.
