Muscle proteolysis is regulated by the ATP-dependent ubiquitin–proteasome system. This system involves ubiquitination of specific proteins, leading to recognition and degradation by the 26S proteasome complex. Ubiquitination requires interactions with ubiquitin related proteins, ubiquitin-activating (E1), ubiquitin-conjugating (E2) and ubiquitin-ligating enzymes (E3) known as ligases. Two muscle specific ubiquitin ligases have been identified, muscle ring finger 1 (MuRF-1) and Atrogin 1. Both ligases are regulated by the Akt1/FOXO1 signaling pathway, and both proteins have been shown to be upregulated prior to the onset of atrophy in multiple models of muscle wasting, including disuse and cachexia.
Human recombinant Atrogin 1 is a 54 kDa protein that includes the full length sequence along with N-terminal His tag and Sumo fusion tag. This Atrogin 1 fusion protein is detected by rabbit polyclonal anti-Atrogin 1 and rat monoclonal anti-Atrogin 1.
Western blot image of human recombinant Atrogin 1 (lanes 1-6). The blot was probed with rabbit polyclonal Atrogin-1 (lanes 1-3) and rat monoclonal Atrogin-1 (lanes 4-6) at 1:1000 (lanes 1 & 4), 1:2000 (lanes 2 & 5), and 1:4000 (lanes 3 & 6).
The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.
*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blotmobilities of known proteins with similar MW.

国内或者国外进口皆可！？看来你不缺钱啊！
这个问题问的过于笼统！
首先，蛋白表达与纯化包括很多种类型，比如原核蛋白表达，哺乳动物蛋白表达，酵母蛋白表达以及昆虫蛋白表达等等，而现在生物实验中常说的蛋白表达纯化通常是指利用大肠杆菌表达系统的原核蛋白表达，这种表达方式比较简单，普遍都可以做。但是如果是指很多种蛋白表达系统的话，可以做的单位就比较少了。
另外，蛋白的表达成功与否还需要取决于蛋白的性质，所以前期一定要问清楚！
