IL-23 alpha protein is part of the IL-6 superfamily and contains IL-23 alpha and IL-12 beta subunits that form a biologically active complex. It has a crucial impact on the differentiation and activation of Th17 cells associated with autoimmune diseases. IL-23 Protein, Rabbit (HEK293, His) is a recombinant protein dimer complex containing Rabbit-derived IL-23 alpha & IL-12 beta Heterodimer protein, expressed by HEK293 , with C-His labeled tag.
