Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验Methods for Studying Interferon Tau Stimulated Genes
Interferon (IFN)τ, a Type I IFN produced by the conceptus trophectoderm, is the pregnancy recognition signal in ruminants that prevents development of the endometrial luteolytic mechanism. In addition, IFNτ acts in a paracrine manner
年耿信笃教授首先将高效疏水相互作用色谱(HPHIC)用于变性蛋白的复性，很好的解决了上述问题，现已成功用于重组人干扰素-g(rhIFN-g)、重组人干扰素-a(rhIFN-a)、人粒细胞集落刺激因子(rhG-CSF)、重组人胰岛素原(proinsulin)、重组牛朊病毒(prion)等重组蛋白以及溶菌酶和核搪核酸酶等标准模型蛋白的复性与同时纯化中。目前，排阻色谱法、离子交换色谱法和亲合色谱法也已用于蛋白质的复性和同时纯化中。与传统的稀释法及透析法比较，用色谱法进行蛋白复性的优点是：①在进样后可很快
干细胞或分化不同阶段的造血细胞在半固体培养基中形成不同的细胞集落，分别命名为G-CSF、M-CSF、GM-CSF、SCF、EPO等。不同CSF不仅可刺激不同发育阶段的造血干细胞和祖细胞增殖的分化，还可促进成熟细胞的功能。 3，干扰素（Interferon, IFN)是某些病毒感染的细胞产生一种物质，可干扰病毒的感染和复制。根据干扰素的来源和结构，可分为IFN-α、IFN-β和IFN-γ，分别由白细胞、成纤维细胞和活化T细胞所产生，具有抗病毒、抗肿瘤和免疫调节等作用。 4，肿瘤
