BioSim™ Ustekinumab (Stelara®) (Human) ELISA Kit

Ustekinumab is a fully human monoclonal antibody that binds with high specificity and affinity to the cytokines interleukin (IL)-12 and IL-23, thereby suppressing IL-12- and IL-23-mediated inflammation associated with psoriasis. Ustekinumab (STELARA®) is the only FDA-approved medicine that targets IL-12 and IL-23, which are thought to be associated with gastrointestinal inflammation in Crohn's disease. BioSim Ustekinumab (Stelara®) ELISA Kit is a sandwich based ELISA kit. Standards and samples are incubated in the microtitre plate coated with the reactant for Ustekinumab (Stelara®). After incubation, the wells are washed. HRP-conjugated probe is added and binds to ustekinumab captured by the reactant on the surface of the wells. Following incubation wells are washed and the bound enzymatic activity is detected by addition of chromogen-substrate. The color developed is proportional to the amount of ustekinumab in the sample or standard. Results of samples can be determined directly using the standard curve.
