简介
The IL-5 Protein, predominantly expressed by T-lymphocytes and NK cells, is crucial for eosinophil survival, differentiation, and chemotaxis. It also affects B-cells, inducing immunoglobulin production, growth, and differentiation. IL-5 Protein activates kinases like LYN, SYK, and JAK2, which signal through RAS-MAPK and JAK-STAT5 pathways. It exists as a disulfide-linked homodimer and interacts with IL5RA and CSF2RB subunits. Animal-Free IL-5 Protein, Human (His) is the recombinant human-derived animal-FreeIL-5 protein, expressed by E. coli , with C-His labeled tag. This product is for cell culture use only.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
Interleukin-5 (IL-5) is a critical cytokine primarily produced by activated T-helper type 2 (Th2) cells and plays a significant role in regulating eosinophil production, differentiation, and activation in the immune response. Elevated levels of IL-5 are associated with various allergic conditions, including asthma, allergic rhinitis, and eosinophilic esophagitis, making it a pivotal target for therapeutic intervention. The study of recombinant IL-5 proteins has gained traction as researchers aim to understand its biological functions and signaling pathways more comprehensively. By producing IL-5 in recombinant systems, scientists can explore its interactions with specific receptors, elucidate its role in eosinophil biology, and investigate its implications in allergic diseases. Furthermore, recombinant IL-5 is also being explored for its potential use in vaccine development and as a biomarker for diagnosing and monitoring allergic conditions. The advancement of biotechnology and protein engineering techniques has paved the way for producing highly purified and biologically active IL-5, fostering research into novel therapeutic approaches aimed at modulating eosinophilic inflammation and improving patient outcomes in allergic diseases. As the understanding of IL-5 and its role in immune regulation deepens, ongoing research into its recombinant forms also aims to inform the development of more targeted therapies that may provide better efficacy and reduced side effects compared to conventional treatments.
