Human Recombinant IL-2 is a monomeric cytokine first identified as a T cell growth factor. It binds to a heterotrimeric IL-2 receptor complex (CD25, CD122, and CD132) on immune cells. This interaction triggers JAK3, STAT5, and AKT signaling pathways that drive cell proliferation and survival. Most IL-2 is secreted by activated CD4+ and CD8+ T cells, with smaller amounts produced by B cells and dendritic cells.
At Apex Scientific, a leading laboratory equipment supplier in South Africa, we provide high-purity Human Recombinant IL-2 (≥ 95% purity) from StemCell Technologies. Manufactured to stringent quality standards, it ensures consistent performance in immunology and stem cell biology research across South Africa.
Role in Immune Regulation
Human Recombinant IL-2 regulates immune responses in several ways. It prevents autoimmunity during T cell development in the thymus by promoting regulatory T cell growth (CD4+ CD25+). It also influences the formation of follicular helper T cells, which support B cell function and antibody production. Furthermore, IL-2 helps control inflammation by inhibiting the differentiation of pro-inflammatory Th17 cells.
Researchers have observed elevated IL-2 levels in diseases such as scleroderma, rheumatoid arthritis, and certain cancers, including gastric and non-small cell lung cancer. However, no disease has been directly linked to a complete deficiency or excess of IL-2.
Applications and Specifications
Human Recombinant IL-2 is a high-purity cytokine used to stimulate T cell proliferation and activate NK cells. It supports hematopoietic progenitor cells and is a standard supplement in T cell culture protocols. In South Africa, researchers use it for experimental assays, immune function studies, and cell therapy development.
