SEQUENCE of the Recombinant Interleukin 18 (IL18)

USAGE of the Recombinant Interleukin 18 (IL18)
Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
STORAGE of the Recombinant Interleukin 18 (IL18)
Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
STABILITY of the Recombinant Interleukin 18 (IL18)
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

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。
