IL-1 beta, Human (His-Avi)

IL-1 beta is a potent proinflammatory cytokine expressed by monocytes, macrophages, and dendritic cells. IL-1 beta plays a key role in inflammation and immunologic reactions[1][2].  IL-1 beta Protein, Human (His-Avi) is produced in  E. coli with a C-Terminal His-tag and a C-Terminal Avi-tag. It consists of 153 amino acids (A117-S269).
