- BackgroundGlutaredoxin-1 (GRX1) is also known as Thioltransferase-1 (TTase-1), GLRX, GRX, GLRX1, which belongs to the glutaredoxin family. GRX1 / GLRX contains one glutaredoxin domain, which exists in either a reduced or an oxidized form. GRX1 / GLRX has a glutathione-disulfide oxidoreductase activity in the presence of NADPH and glutathione reductase and functions as electron carriers in the glutathione-dependent synthesis of deoxyribonucleotides by the enzymeribonucleotide reductase.

最好能说得具体点,小弟对此几乎一窍不通
谢谢
1. 粗纯:将制备抗体的血清或是腹水,细胞上清,直接用盐析法进行处理,这样可以将这些物质里面的其他杂质去掉,获得蛋白的成分,但是由于是粗纯,里面会混有大量的其他蛋白,这样获得的抗体,纯度较低,用于实验中背景比较高。
2.通用型纯化:用抗体结合蛋白Protein A,Protein G或者Protein L。因为不同来源的抗体和这些抗体结合蛋白的结合能力不同,所以需要根据抗体来源选择使用哪种抗体将诶和蛋白最好。对于有一些单链抗体,则多半使用protein L来进行纯化。经过抗体结合蛋白的亲和纯化后,溶液中基本只保留了抗体的成分,其他蛋白都去掉了,抗体纯度可以比较高。相对来说,这种方法是大规模抗体制备中,用得最多的纯化方法,很多抗体公司都采用这种方法来对抗体进行纯化。
3.特异型纯化:但是有些抗体,需要纯度特别高,特异性特别好,就不能简单采用上述两种方法进行纯化了。必须要通过将抗原固定制备成特异的亲和纯化柱,再纯化抗体。这个时候得到的就全是针对一种抗原的抗体了,特异性最好。当然,由于牵涉到抗原固定等操作,成本相应是最高的。
