and FAQs
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...

Sample type: Cell culture supernatant
Sample species: Human
Sample dilution: No dilution
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...

Target Background
(From Uniprot)
- IL-5 is expressed intrathecally in tick-borne encephalitis, but its pathogenetic role remains unclear.
- eosinophilia in FE is secondary to dysregulation of IL-5 production in PBMC (and their component subsets).

- Data indicate that interleukin 5 (IL-5)-associated single nucleotide polymorphisms (SNPs) were not associated with carotid intima-media thickness.
- Post-liver transplant patients with food allergy showed a unique cytokine profile in response to various stimuli, with extremely elevated IL-5, low IL-10 secretion.
- Production of IL-5 in response to both extract and the Bet v1-derived peptide mix strongly suggested that T cells were a major source of IL-5.
- It has been shown in this study that the level of IL-5, one of the markers of eosinophilic inflammation, is higher in EBC of children with atopic asthma than in those with nonatopic asthma.
