背景介绍
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a crucial protein governing the circulating levels of low density lipoprotein-cholesterol (LDL-C), by virtue of its pivotal role in the degradation of the LDL receptor (LDLR). PCSK9 is expressed in the kidney and lung. It is synthesized as a 72 kDa immature precursor that undergoes autocatalytic cleavage in the endoplasmic reticulum to generate a 63 kDa mature protein. The cleaved N-terminal fragment remains associated with the mature protein and is necessary for its secretion, allowing it to circulate in the blood. The ability of PCSK9 to regulate a diverse group of cell-surface proteins hinted that it might also be able to influence additional membrane proteins that are important in anti-tumour immune responses. Targeting PCSK9 to treat cancer is also attractive because two neutralizing antibodies against it, evolocumab and alirocumab, have already been approved for human clinical use to lower cholesterol levels.

因此，综合来说，EarthOx的GST标签抗体 （货号#E022040）是一款同时具有高特异性、高灵敏度、多应用类型以及性价比的GST标签抗体。同时，我们也提供其他品牌的GST标签抗体，如Proteintech的GST多克隆抗体 ――GST PolyClonal Antibody（货号#10000-0-AP）以及Abcam、Santa等多种GST标签抗体产品。更多GST标签抗体以及其他如His、HA、Myc、GFP、Flag等其他标签抗体，请电话垂询。美国EarthOx品牌是一家提供高性价比免疫学和细胞
实验，请根据说明书列出已验证的种属来选择适合你实验的抗体。 （4）样本蛋白的结构性质。了解样本蛋白的结构性质有助于选择最合适的抗体，待测样本蛋白的结构域和样本在提取和处理过程中是否会变性，蛋白空间构象的改变，会影响抗体的免疫亲和反应。 （5）单多克隆抗体的选择。市面上的抗体还是以多克隆抗体为主，一般单克隆抗体特异性强，但亲和力相对小，检测抗原灵敏度相对就低；而多克隆抗体特异性稍弱，但抗体的亲和力强，灵敏度高，但易出现非特异性染色（可以通过封闭等避免
发生，最好在特异性抗体处理切片之前，选择与二抗种属相同的非免疫血清封闭电荷，阻止一抗与之结合，抑制非特异性背景着色。常用方法是用2%～10%羊血清或2%～5%牛血清白蛋白在室温下作用10~30分钟。但应注意此种结合不牢固，所以最好不要冲洗，倾去余液直接加一抗。SABC或SP免疫组织化学试剂盒中常配有非免疫血清。 7．第一抗体孵育 滴加特异性一抗于切片上，4℃孵育24～48小时，或室温孵育过夜，也可在37~C孵育1～2小时。之后，用PBS冲洗3次，每次5分钟。一抗分为多克隆抗体和单克
