背景介绍
Programmed cell death 1 (PD-1, also known as CD279) is an immunoinhibitory receptor that belongs to the CD28/CTLA-4 subfamily of the Ig superfamily. It is a 288 amino acid (aa) type I transmembrane protein composed of one Ig superfamily domain, a stalk, a transmembrane domain, and an intracellular domain containing an immunoreceptor tyrosine-based inhibitory motif (ITIM) as well as an immunoreceptor tyrosine-based switch motif (ITSM) (PMID: 18173375). PD-1 is expressed during thymic development and is induced in a variety of hematopoietic cells in the periphery by antigen receptor signaling and cytokines (PMID: 20636820). Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function (PMID: 19426218). It is critical for the regulation of T cell function during immunity and tolerance. Blockade of PD-1 can overcome immune resistance and also has been shown to have antitumor activity (PMID: 22658127; 23169436). It has been reported that PD-1 is heavily glycosylated and migrates with an apparent molecular mass of 47-55 kDa on SDS-PAGE , which is larger than its predicted mass of 32 kDa (PMID: 8671665; 17640856; 17003438).

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
