背景说明:

Involved in double-strand break repair and/or homologous recombination. Binds RAD51 and potentiates recombinational DNA repair by promoting assembly of RAD51 onto single-stranded DNA (ssDNA). Acts by targeting RAD51 to ssDNA over double-stranded DNA, enabling RAD51 to displace replication protein-A (RPA) from ssDNA and stabilizing RAD51-ssDNA filaments by blocking ATP hydrolysis. Part of a PALB2-scaffolded HR complex containing RAD51C and which is thought to play a role in DNA repair by HR. May participate in S phase checkpoint activation. Binds selectively to ssDNA, and to ssDNA in tailed duplexes and replication fork structures. May play a role in the extension step after strand invasion at replication-dependent DNA double-strand breaks; together with PALB2 is involved in both POLH localization at collapsed replication forks and DNA polymerization activity. In concert with NPM1, regulates centrosome duplication. Interacts with the TREX-2 complex (transcription and export complex 2) subunits PCID2 and SEM1, and is required to prevent R-loop-associated DNA damage and thus transcription-associated genomic instability. Silencing of BRCA2 promotes R-loop accumulation at actively transcribed genes in replicating and non-replicating cells, suggesting that BRCA2 mediates the control of R-loop associated genomic instability, independently of its known role in homologous recombination.

该产品为 BRCA2 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:K112954P。
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。
