Description

Interleukin-5 (IL-5) is a cytokine that regulates eosinophil biology and B-cell differentiation. Originally identified as a B-cell differentiation factor and T-cell replacing factor, IL-5 is primarily produced by activated T-helper 2 cells and serves as a key mediator in allergic and inflammatory responses. The cytokine promotes eosinophil development, activation, and survival, making it an important factor in asthma, allergic rhinitis, and other eosinophil-associated disorders. IL-5 also functions as an eosinophil differentiation factor, regulating the maturation and recruitment of these c...

Review: I used this kit (CSB-E04636h) to detect human cell culture supernatants (normal group, undiluted). The absorbance values of the standard curve ranged from 0.1 to 2.36, and the OD values of all test samples also fell within this linear range. The results show that the kit has high sensitivit...
