无动物成分的重组人LIF

无动物成分的重组人LIF 英文名称：Animal-Free Recombinant Human LIF 规格：5ug 价格：￥1,395 货号：AF-300-05-5ug 不含动物成分蛋白/ANIMAL-FREE PROTEINS 产品描述： Animal-Free Recombinant Human LIF LIF is a pleiotrophic factor produced by multiple cell types, including T cells, myelomonocytic lineages, fibroblasts, liver, heart and melanoma. LIF promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. Other activities include the stimulation of acute phase protein synthesis by hepatocytes, stimulation of differentiation of cholinergic nerves, and suppression of adipogenesis by inhibiting the lipoprotein lipase in adipocytes. While human LIF is active on mouse cells and is widely used in the maintenance of murine ESC to prevent spontaneous differentiation, mouse LIF is not active on human cells due to its inability to bind to the human LIF receptor. Recombinant Human LIF is a 19.7 kDa protein containing 180 amino acid residues, including three disulfide bonds. Manufactured using all Animal-Free reagents.
