Interleukin-2 (IL-2) is a cytokine that plays a crucial role in the immune system by promoting the growth, differentiation, and survival of certain immune cells, including T cells and B cells. The Interleukin-2 receptor (IL-2R) is a heterotrimeric protein complex composed of three subunits: alpha (IL-2Rα or CD25), beta (IL-2Rβ), and gamma (IL-2Rγ). The alpha subunit, also known as CD25, is particularly important for the high-affinity binding of IL-2.
The soluble form of the IL-2 receptor alpha (sIL-2Rα) is a truncated version of the membrane-bound receptor that is released into the bloodstream. This soluble receptor can bind to IL-2, modulating its availability and activity in the immune system. Elevated levels of sIL-2Rα are often associated with various autoimmune diseases, infections, and certain types of cancer, making it a valuable biomarker for these conditions.
Human recombinant sIL-2Rα is a laboratory-produced version of the soluble IL-2 receptor alpha. It is typically produced using recombinant DNA technology, where the gene encoding the human IL-2Rα is inserted into an expression system, such as Escherichia coli (E. coli) or Chinese Hamster Ovary (CHO) cells. The recombinant protein is then purified for use in research and clinical applications.
The production of human recombinant sIL-2Rα involves several steps:
Human recombinant sIL-2Rα has several important applications:
