IL-21 is a cytokine with immunomodulatory capabilities that orchestrates the transition from innate to adaptive immunity. It induces the production of IgG (1) and IgG (3) by B cells, thereby forming a humoral immune response. IL-21 Protein, Mouse (His) is the recombinant mouse-derived IL-21 protein, expressed by E. coli , with N-6*His labeled tag.
