常见问题

超敏 ECL 发光液(Enlight™-Plus)适用于哪类检测?

用于辣根过氧化物酶(HRP)标记的蛋白或核酸检测,是 Western Blot(免疫印迹)常用的化学发光底物,已被超 300 家实验室长期应用。

超敏 ECL 发光液有什么特点?灵敏度能到多少?

含高灵敏的发光增强剂,检测级别可以达到 pg 级,适合微量蛋白检测;采用精准的发光底物,有效降低发光试剂造成的非特异发光和背景发光;发光持续时间长,可从容进行曝光操作。

超敏 ECL 发光液怎么使用?抗体稀释多少?

推荐一抗(储存液 1mg/ml)稀释 1:1000-1:5000(0.2-1.0μg/ml)、二抗稀释 1:2000-1:10000(0.1-0.5μg/ml)。将 Buffer A 与 Buffer B 按 1:1 新鲜混合成工作液(每 cm² 膜约 0.125ml)。洗好的膜用滤纸吸去多余洗液,保持湿润但无明显液滴,放入工作液中室温孵育几十秒到 1 分钟;取出后吸去多余发光液,用保鲜膜包好,推荐用化学发光成像仪检测,也可用 X 光胶片曝光。

超敏 ECL 发光液曝光时间多长?

化学发光成像仪(推荐):先通过软件预曝光几秒至几分钟,确定最佳曝光时间;如提示信号过饱和应缩短曝光时间,以保证条带可用于定量分析。X 光胶片:在暗室中首次曝光 10-30 秒,信号弱或无信号时逐步延长至 1 分钟、5 分钟、10 分钟,信号过强或背景过高时缩短至 5-10 秒,或适当提高抗体稀释倍数。发光强度随时间逐渐衰减,后续胶片需适当延长曝光时间。

背景高怎么办?

① 优化一抗、二抗稀释比例,背景高时提高稀释倍数;② 使用生物素-亲和素(Biotin-Streptavidin)检测系统或检测磷酸化蛋白时,用 BSA 代替脱脂奶粉进行封闭和抗体稀释(脱脂奶粉含内源性生物素,且其主要成分酪蛋白为磷蛋白);③ 整个实验过程中勿使膜变干;④ 使用高质量保鲜膜,包膜时去除气泡和褶皱。

使用时有哪些注意事项?

吸取 Buffer A 和 Buffer B 必须使用干净且专用的移液枪头,切勿混用,以防 A、B 液在试剂瓶中交叉污染导致整瓶失效;用剩的工作液不得倒回原试剂瓶,用后及时盖紧瓶盖。洗膜液、封闭液、抗体稀释液及回收的 HRP 偶联抗体中均不得含有 NaN₃(NaN₃ 抑制 HRP 活性)。发光液请避光保存,使用 X 光胶片检测时在暗室操作。

同一张膜能用超敏 ECL 检测多种蛋白吗?

可以。Enlight™-Plus 不破坏膜上蛋白。曝光后用 PBST 或 TBST 洗涤 3 次(每次 10 分钟)去掉发光液,再用抗体洗脱液(Stripping Buffer)去除膜上原有的一抗和二抗,洗涤后重新封闭,然后从一抗杂交开始操作。洗脱后可先加发光工作液曝光,确认无残留信号。

超敏 ECL 发光液如何运输保存?有效期多久?

常温运输,避光储存于 4℃,有效期 12 个月。

超敏 ECL 发光液有哪些规格?

提供 100ml(货号 17100,Buffer A、B 各 50ml)、200ml(货号 17200,各 100ml)、500ml(货号 17500,各 250ml)三种规格。

超敏 ECL(Plus)和增强型 ECL 有什么区别?怎么选?

两者都是英格恩 HRP 化学发光底物,用于 Western Blot。增强型 Enlight™ 侧重发光特异性,发光快速而稳定,适合常规及中、高丰度蛋白检测;超敏型 Enlight™-Plus 检测级别可达 pg 级,适合低丰度蛋白检测,通常所需曝光时间更短,且发光持续时间长,便于多次曝光。用超敏型检测高丰度蛋白时,需提高抗体稀释倍数,以防信号过饱和。规格上增强型另有 1000ml 大包装。

超敏 ECL 和增强型 ECL 怎么选?

两款分别是 Enlight™-Plus 超敏发光检测试剂盒(超敏 ECL)与 Enlight™ 特异发光检测试剂盒(增强型 ECL),按靶标丰度和实验需求选:
Enlight™-Plus(超敏 ECL,货号 17100/17200/17500):含高灵敏的发光增强剂,检测级别可以达到 pg 级;采用精准的发光底物,有效降低非特异发光和背景发光;发光持续时间长,便于从容完成实验操作。适合低丰度靶标、微量样品,或需要较长发光窗口的实验。
Enlight™(增强型 ECL,货号 29050/29100/29500/291000):核心定位是发光的特异性与稳定性,发光快速而稳定,含独特的发光增强剂、微弱信号也能检测。适合常规丰度靶标,重点是避免非特异条带、背景条带与发光淬灭。
一个可直接对照的硬指标:X 光胶片首次曝光时间,Enlight™-Plus 为 10-30 秒,Enlight™ 为 1 分钟。
两款都不破坏膜上蛋白,曝光后经抗体洗脱(Stripping)处理,可对同一张膜进行多种蛋白的再次杂交。

Enlight™-Plus 发光工作液怎么配?一张膜需要多少?

新鲜配制:将 Buffer A 和 Buffer B 按 1:1 比率混合制成发光工作液,每 1cm² 膜需要 0.125ml 发光工作液,转移到清洁的塑料小盒中。
将漂洗过的膜吸去多余洗液,保持表面湿润但无明显液滴(残留液滴会稀释发光工作液),切勿使膜变干;转移至工作液中完全浸泡,轻轻摇晃,室温孵育几十秒到 1 分钟。

Enlight™-Plus 推荐的抗体稀释度是多少?

储存液浓度为 1mg/ml 时:一抗推荐稀释度 1:1000-1:5000,或 0.2-1.0μg/ml。
二抗推荐稀释度 1:2000-1:10000,或 0.1-0.5μg/ml。

Enlight™-Plus 用 X 光胶片检测,曝光时间怎么调?

在暗室中将包好的膜蛋白面朝上固定于 X 光片暗盒内,放入一张 X 光胶片,首次曝光 10-30 秒后取出显影。
信号弱或无信号时:逐步延长至 1 分钟、5 分钟、10 分钟。
信号过强或背景过高时:缩短至 5-10 秒,或适当提高抗体稀释倍数。
由于发光强度随时间逐渐衰减,后续胶片的曝光时间需适当延长。

Enlight™-Plus 用化学发光成像仪怎么检测?

将包裹好的膜蛋白面朝上放入化学发光成像仪(CCD)样品台,选择化学发光(Chemiluminescence)模式。
先通过软件预曝光几秒至几分钟,根据信号强弱确定最佳曝光时间;若软件提示信号过饱和,应缩短曝光时间,以保证条带强度可用于定量分析。
也可使用软件的连续/累积曝光功能获取不同曝光时间的系列图像,择优选取。
