背景介绍
CREB1, also named as CREB, belongs to the bZIP family, containing one bZIP domain and one KID (kinase-inducible) domain. This protein binds the cAMP response element (CRE), a sequence present in many viral and cellular promoters. CREB stimulates transcription on binding to the CRE. This protein is stimulated by phosphorylation. Phosphorylation of both Ser-133 and Ser-142 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-133 allows CREBBP binding. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-133 phosphorylation. CREB1 is sumoylated by SUMO1. Sumoylation on Lys-304, but not on Lys-285, is required for nuclear localization of this protein. Sumoylation is enhanced under hypoxia, promoting nuclear localization and stabilization. Defects in CREB1 may be a cause of angiomatoid fibrous histiocytoma (AFH), a distinct variant of malignant fibrous histiocytoma that typically occurs in children and adolescents and is manifest by nodular subcutaneous growth. A chromosomal aberration involving CREB1 is found in a patient with angiomatoid fibrous histiocytoma. Translocation t(2;22)(q33;q12) with CREB1 generates a EWSR1/CREB1 fusion gene that is most common genetic abnormality in this tumor type. CREB1 exists some isoforms and range of calculated molecular weight of isoforms are 35-37 kDa and 25 kDa, but the modified CREB1 protein is about 43 kDa (PMID: 25883219 ).

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
