一、中文名称:Anti-Z-DNA Antibody (Z22) (RGK24302)小分子抗体,抗Z-DNA抗体
二、产品描述
Anti-Z-DNA抗体(Z22)是一种特异性识别左旋Z型DNA构象的单克隆抗体,能够高亲和力结合Z-DNA的独特骨架结构及碱基暴露表位,但对B型DNA无交叉反应。在生物医学研究中,Z22作为关键工具广泛应用于:(1)染色质构象分析:通过免疫荧光或免疫共沉淀技术(如ChIP-seq)定位基因组中Z-DNA动态区域,揭示其在转录调控、染色质重塑及转座子激活中的作用;(2)疾病机制研究:检测自身免疫性疾病(如系统性红斑狼疮)患者血清中Z-DNA抗体的水平,辅助探究其与抗核抗体病理活性的关联;(3)癌症生物学:追踪癌基因启动子区Z-DNA的形成与DNA超螺旋应力、基因组不稳定性之间的调控网络;(4)病原体防御:解析病毒(如痘病毒)利用Z-DNA结构逃逸宿主免疫识别的分子策略。该抗体的高构象特异性为解析DNA拓扑异构化在表观遗传和疾病发生中的功能提供了精准探针。
