This article elaborates in detail on the Human IL-4/IL-4R binding detection kit based on Bio-Layer Interferometry (BLI), systematically introducing its applications in analyzing Type I/II receptor complexes, evaluating the efficacy of therapeutic antibodies and small-molecule inhibitors, and providing a quantitative analysis tool for research and drug development in the fields of allergies, asthma, and immune diseases.

The core pathogenesis of allergic diseases lies in the abnormal activation of the type 2 inflammatory pathway. This pathway, primarily mediated by T helper 2 (Th2) cells, regulates the direction of the immune response through a complex cytokine network. As a crucial subset of CD4+ T cells, Th2 cells differentiate into effector cells upon allergen stimulation and initiate and sustain the type 2 immune response by secreting the key cytokines interleukin (IL)-4, IL-5, and IL-13.
