Descrição detalhada : Product Source: rtLIF is expressed in E. coli as a fusion protein with GST using the pGEX expression system, cleaved from GST moiety with thrombin and purified by ion-exchange chromatography., Leukemia Inhibitory Factor (LIF) is a lymphoid factor which promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo., Rat LIF (rtLIF) is a 22.1 kDa protein containing 202 amino acid residues that exhibits 91% amino acid sequence identity with murine LIF(Takahama etal 1998).Analysis of the secondary structure of rat and murine LIF indicates a difference in the two dimensional structure of both proteins. Studies have shown that rtLIF is more effective in maintaining the undifferentiated phenotype of rat ES cells than similar concentrations of murine LIF (Takahama, et al 1998).
