产品介绍
这种双功能 Cy3 生物素偶联物在与蛋白质或核酸靶标结合时表现出优异的抗生物素蛋白结合的能力和很强的荧光。它在亲和素和链霉亲和素四聚体的高亲和力、快速结合和非协同结合方面具有与天然生物素相似的亲和素结合特性。 Cy3 Biotin 可用于检测和量化抗生物素蛋白、链霉抗生物素蛋白或中性抗生物素蛋白的生物素结合位点。该试剂克服了常用的 Biotin-4-fluorescein 的主要缺点，例如在水性介质中溶解度差和 pH 依赖的吸光度和发射。 Cy3 Biotin 是一种水溶性试剂，其红色荧光在 pH 4 到 pH 10 之间不受 pH 影响。生物素部分和荧光标签之间的柔性 PEG 间隔物可大限度地减少与抗生物素蛋白、链霉抗生物素蛋白或中性抗生物素蛋白结合所涉及的空间位阻。
