Interleukin-6 (IL-6) is a multifunctional cytokine that regulates immune responses and inflammation. It is produced by various cells, including immune cells such as T cells and macrophages, as well as non-immune cells like fibroblasts and endothelial cells.

Human IL-6 has a molecular weight of 20.9 kDa. This protein is animal origin-free, carrier-free and tag-free to ensure its purity with exceptional lot-to-lot consistency. IL-6 is suitable for the culture of reproducible and high-quality hematopoietic stem cells and other relevant cells.
