In order to accelerating the drug developments of IL-4/ IL-4Rα, ACROBiosystems has developed IL-4Rα: IL-4 inhibitor screening kit using sandwich ELISA method based on unique biotinylated IL-4 and IL-4Rα proteins, which can used in antibody/small molecular inhibitor screening and QC release. 

★ Accurate and reliable: Verified raw materials of the kit with high batch-to-batch consistency ensures stable and reliable experimental results, which is more conducive to long-term development and optimization of verification experiments.

★ Fast and efficient: By employing the biotin pre-labeled proteins, we eliminate the time-consuming labeling process, and greatly simplify the experimental procedures. Besides, saving time for method establishment and validation as the method is fully validated.

★ Reduce interference: The matrix interference is small, and the interference caused by DMSO to the system is verified to ensure that kit can be used to screen small-molecules/macromolecular inhibitors.

★ High repeatability: Our biotin labeling platform produces biotinylated proteins are using site-specific labeling, and the more stable labeling method ensures minimal lot-to-lot variation and the stability of the kit.
