    产品特性

    纯度 >95% as determined by reducing SDS-PAGE.
    内毒素< 1.0 EU per µg as determined by LAL test.
    保存 Lyophilized protein should be stored at -5~-20℃, stable for one year after receipt. Reconstituted protein solution can be stored at 2~8℃ for 2~7 days. Aliquots of reconstituted samples are stable at -5~-20℃ for 3 months.
    运输 Ambient temperature or ice pack.
    制剂Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
    复融Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

    背景介绍

    Leukemia Inhibitory Factor (LIF) is a lymphoid factor that 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. Human and murine mature LIF exhibit a 78% sequence identity at the amino acid level. Human LIF is equally active on human and mouse cells. Murine LIF is approximately 1000 fold less active on human cells than human LIF.
