产品介绍
储存缓冲液:PBS, pH7.4±0.2 产品介绍: UltraBio™封闭液 (PBS) 是在磷酸盐缓冲液 (PBS) 中配制一种专有高度纯化的单一蛋白质,用于Western blot和 ELISA检测中快速有效地封闭多余的结合位点。它们与广泛的抗体,抗体组合和其他蛋白质检测和分析系统兼容。系列UltraBio™封闭液不含白蛋白或内源性生物素,因此与生物素/亲和素系统兼容。为了便于 Western blot 使用,系列产品包括封闭缓冲液含 0.05%的去垢剂 Tween 20 或 Triton X-100,这可以提高许多 Western blot 检测系统的封闭性能。对于 ELISA 包被板封闭,无需使用含去垢剂的封闭液,但为了提高检测的信噪比,推荐使用含有去垢剂的封闭液稀释一抗和二抗。 UltraBio™封闭液提供形式: 溶于PBS和溶于TBS,含/不含Tween-20和Triton X-100。 使用说明: UltraBio™封闭液 (PBS) 为即用型封闭液,平衡至反应温度后摇匀后使用。 ELISA微孔板封闭步骤 (示例): 封闭 ELISA 包被板时,推荐使用不含有 Tween 20 或 Triton X-100 的 Blocking Buffer。 1、抗原或抗体包被后; 2、洗涤:用PBS/TRIS washing buffer (不含表面活性剂) 洗去多余的蛋白,重复2次; 3、封闭:加入适量UltraBio™封闭液,20-37℃孵育30 min; 4、检测:吸去 (或拍干) 封闭液后,直接用于下游检测实验;或在37℃的烘箱中烘干2-4h,彻底干燥后密封保存于2-8℃。 Western blot 封闭步骤 (示例): 推荐使用含有 Tween 20 或 Triton X-100 的 Blocking Buffer。 1、蛋白转移后,将膜从转移装置上取下,然后在去离子水中洗涤5min,去除所有转移缓冲液; 2、加入足够的UltraBio™封闭液以覆盖膜。对于直接方法 (即使用酶标记的一抗检测),在室温下摇晃孵育1-5min。对于间接方法 (即使用酶标记的二抗检测),室温下摇匀孵育15-30min; 3、继续进行下游检测的Western blot程序。
