TSLP is a protein in the cytokine family, typically expressed in epithelial cells at barrier surfaces such as the lungs, skin, and intestines. TSLP is primarily produced by non-hematopoietic cells, including fibroblasts, epithelial cells, and various types of stromal or stroma-like cells.

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.

Protein-labeled receptors, as the molecular cornerstone for organisms to perceive the environment and regulate functions, exemplify the translational path from basic science to clinical medicine. Every deeper understanding of receptor structure and function directly translates into clearer insights into disease mechanisms and more precise therapeutic tools.

Asthma is a common chronic respiratory disease characterized by chest tightness, shortness of breath, and wheezing, which seriously affects the quality of life of patients. Among them, type 2 asthma is closely related to allergic sensitization, accompanied by typical features such as increased levels of cytokines (IL-4, IL-5, IL-13) secreted by helper T cell 2 (Th2), increased eosinophils, and activated mast cells.
