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.
C4结合蛋白α(C4BPα)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验网络 二、C4结合蛋白 C4结合蛋白(C4bp)是一种含量丰富的可溶性血清糖蛋白,分子量为550kDa,1977年由Ferreira等所报道。其分子结构模式现多以Dahlback等(1983)描述的“蜘蛛样”(spiderlike)结构来分析其结构及功能。C4bp由8个亚单位组成,电镜下观察形似蜘蛛,其中有7条分子量相同(均
,或者可以表达以产生重组蛋白。pET-32α(+)载体系列用于表达与109 aa Trx•Tag™硫氧还蛋白融合的肽序列。它属于一种表达系统,可在其激活后产生所需的蛋白质。插入原核宿主细胞。原核细胞如大肠杆菌因为它们廉价,快速的生物量积累和简单的工艺规模扩大,因此是外源蛋白表达的首选宿主。在本文中,我们将重点总结这种在我们的实验室中使用的有用技术。表达后pET-32α(+)载体的构建,蛋白质表达和蛋白质纯化将在本文中详细描述。获得用于构建载体的外源DNA片段插入载体的DNA通常可以使用聚合酶链式反应(PCR
