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.
