Ustekinumab Antibody | 18334

Ustekinumab Antibody | 18334 gallery image 1

ELISA demonstrating the specificity of HCA209 using various antigens as coating reagents.
Antigens were coated at 5 µg/mL on a microtiter plate overnight. After washing and blocking with 5% BSA, the anti-Ustekinumab antibody HCA209 (AbD18334; 20µL from a 2µg/mL solution) was added followed by an anti-His-tag antibody conjugated to HRP in HiSPEC buffer (BUF049). Detection was performed using QuantaBlu™ fluorogenic peroxidase substrate

Inhibition of Ustekinumab binding to IL-23 by HCA209.
IL-23 (1.0 µg/mL) was used as the coating antigen followed by a pre-incubated mixture of the anti-idiotypic antibody HCA209 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

HCA209 PK assay - bridging format.
Anti-Ustekinumab antibody HCA209 (AbD18334) 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 QuantaBlu™ fluorogenic peroxidase substrate. Data is shown as the mean of three measurements

      • Ustekinumab (branded as Stelara®) is a fully human monoclonal antibody drug (IgG1/kappa) that has been approved for treatment of moderate to severe psoriasis. Ustekinumab is also being investigated for the treatment of psoriatic arthritis, for multiple sclerosis and sarcoidosis. Studies indicate that it may also have potential for treating severe Crohns disease.
        Ustekinumab is directed against the p40 subunit of interleukin-12 and interleukin-23 and acts by blocking the binding of these two cytokines to, and preventing activation of, T-lymphocytes.

        Clone 18334 is an anti-idiotypic antibody that specifically recognises the Ustekinumab monoclonal antibody and inhibits the binding of Ustekinumab to its target. It can be used to measure Ustekinumab levels in serum from patients.

        Clone 18334 is an ultra-high affinity anti idiotypic antibody.The monovalent intrinsic affinity of this antibody was measured as KD=0.4 nM by real time, label-free molecular interaction analysis using an Attana A200 instrument on immobilized Ustekinumab.
