The product contains the polyhedrin protein co-crystalized with Mouse IL-3. Also known as Interleukin-3, IL-3 is a cytokine that is produced by activated T cells and mast cells. It induces the differentiation of hematopoietic stem cells into myeloid precursor cells, such as erythrocyte, megakaryocyte, granulocyte, monocyte, and dendritic cells. IL-3 also functions in the nervous system and is important during the B-1 cell regulation of chronic inflammatory diseases.
