背景说明：

Nuclear receptor coactivator 4 (NCOA4) also named androgen receptor (AR) coactivator ARA70， RFG and ELE1， is a putative co-activator that specifically enhances the activity of the androgen receptor. In human thyroid carcinomas， the Ret proto-oncogene fuses to ARA70 to form Ret/PTC3 by an intrachromosomal inversion of chromosome 10 in vivo. ARA70a can function as a ligand-enhanced co-activator of PPARg in adipocytes. However， PPARg-ARA70 transactivation can be squelched by AR， which suggests cross talk between PPARg- and AR-mediated response. ARA70a has no intrinsic transcription activation domain or histone acetyltransferase activity， but it interacts with histone acetyltransferase， p/CAF， CBP and p300/CBP-associated factors， and the basal transcription factor TFIIB. The interaction between ARA70 and AR occurs through the ligand-binding domain. The presence of ARA70 can enhance the androgenic activity of 17-b Estradiol (E2) and antiandrogens toward AR. ARA70 may be involved in prostate carcinogenesis and ovarian cancer and may serve as a key mediator of estrogen-androgen synergism.There are several isoforms of ZGPAT that are produced as a result of alternative splicing events. ARA70a is widely expressed， and its expression is highest in testis and adipose tissues， whereas ARA70b (The shorter variant， results from an internal 985-bp deletion.) is solely expressed in the testis.This antibody is a rabbit polyclonal antibody raised against the N-400aa of human NCOA4 protein.

该产品为 NCOA4 抗体的抗原肽，在抗体检测、纯化时作为封闭肽使用，对应抗体货号为：K118042P。
抗体封闭肽是一类专门用于免疫学检测体系的功能性合成多肽，其核心作用是通过特异性结合干扰性抗体或非特异性结合位点，从而降低实验背景信号，提高检测结果的准确性和可靠性。它并不直接识别目标抗原，而是充当一种“分子屏蔽层”，封闭那些可能导致假阳性或假阴性结果的非特异性相互作用。
在功能层面，抗体封闭肽主要具备两大特性。一是高亲和力的特异性中和能力——其氨基酸序列与检测体系中可能引起交叉反应的抗体表位完全相同或高度同源，因此能够优先与这些干扰抗体结合，占据其活性位点。二是物理屏蔽作用，即在不干扰靶标抗原与检测抗体正常识别的前提下，封闭固相载体或捕获分子上的空缺结合区域，减少杂蛋白或杂抗体的非特异性吸附。
在应用层面，抗体封闭肽广泛应用于各类免疫分析技术中，包括酶联免疫吸附测定、蛋白质印迹、免疫组化以及免疫层析试纸条等。在自身抗体检测、生物制剂的免疫原性分析以及多重免疫检测方法开发中，它能够有效消除由异嗜性抗体、抗物种抗体或样本基质效应引起的背景干扰。此外，在基于标签融合蛋白的表达检测以及抗体亲和纯化流程中，封闭肽同样扮演着关键角色，可作为竞争性洗脱剂或信号校正控制组使用。
