Overview

本产品为浓缩型,专为WB封闭环节PVDF/NC转印膜而设计,此封闭液无蛋白源,无内源的磷酸化蛋白及生物素,对磷酸化抗体及生物素检测不会产生干扰,避免了与抗体发生交叉反应,最大程度地降低了背景。
无蛋白快速封闭液 (5×) 仅仅封闭膜的空白处,不与膜上蛋白产生非特异性结合,不会屏蔽膜上蛋白的抗体识别位点,抗体获得更高的信号,提高了抗体检测灵敏度,封闭时间仅需8分钟,效果优于脱脂奶粉、BSA、酪蛋白等传统封闭液。

产品特色:
快速高效:封闭时间仅需8分钟。
节约抗体:仅仅封闭膜的空白处,不与膜上蛋白产生非特异性结合,提高了抗体检测灵敏度。
无蛋白源:不含蛋白源及生物素,避免交叉反应,更适用于磷酸化抗体及生物素检测系统。

操作步骤:
1. 完成转膜后,将转印膜放入孵育容器中,根据膜的大小,加入适量体积的封闭液(1×),需完全浸没覆盖转印膜(一般加入10-20ml左右即可),置于水平摇床上,轻轻振荡,室温封闭8分钟。
2. 取出封闭完成的转印膜,用洗涤液冲洗 2-3 次,即可用于一抗孵育等后续 WB实验。

注意事项:
1. 本封闭液为5×封闭液,使用时用超纯水稀释5倍使用。
2. 一般用于 PVDF 膜或 NC 膜的封闭时间为8分钟,对于背景低的抗体,可以缩短到 5 分钟,背景高的抗体,可以延长封闭时间至30分钟。
3. 如果本封闭液不适合您的检测系统,请更换其它封闭液,如:BSA 或脱脂奶粉等,没有任何一种封闭液是适用于所有实验体系的。
4. 本产品仅科研使用,实验时请穿实验服并戴一次性手套操作。
