IL-3, also known as Interleukin-3, is a cytokine that is produced by activated T cells and mast cells. It plays a crucial role in regulating the growth, differentiation, and function of various cell types in the immune system. human IL-3 is an important cytokine that regulates the growth, differentiation, and function of immune cells. Its study contributes to our understanding of immune system regulation and its potential applications in immunotherapy and disease treatment. Product Properties
