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.

文献和实验摘要 Groundbreaking work demonstrated that ectopic expression of four transcription factors, Oct4, Klf4, Sox2, and c-Myc, could reprogram murine somatic cells to induced pluripotent stem cells (iPSCs) (Takahashi and Yamanaka, 2006), and human
比较常见的。在不同的细胞环境下,某个转录因子经历不同的修饰(如磷酸化和去磷酸化,或者通过与其它蛋白的结合),可获得不同的转录活性。在真核细胞中,抑制或激活难以由单一蛋白来实现,通常依靠“团队”复合体来完成。 但是难于理解的地方在于:在同样的胞内环境中,同样的转录因子(如上面提到的Oct4)行使了相反的功能。如下图。 个人想到的解释是: 1: 转录因子与DNA序列的结合改变了自身构象,从而改变了其对沉默或激活复合物的亲和力; 2: 与其它转录因子的协同作用决定是激活
● 转录因子与2012年诺贝尔奖2012年的诺贝尔生理学或医学奖得主山中伸弥,在小鼠成纤维细胞中表达Oct3/4、Sox2、c-Myc以及Klf4四种转录因子,将成纤维细胞逆转形成多能干细胞(iPS),进一步揭示了转录因子在生物学研究中的重要研究价值。 每年的诺贝尔奖都会受到举世瞩目,而其获奖内容亦会引领新一轮新的研究热潮。 不想out的科学家们,你们还在等什么?! ● 什么是转录因子?转录因子(Transcription factor,TF)是一类能与特异性DNA序列结合
