λ DNA/HindIII

● 产品编号及规格：

    RTM421-02      100次  (2×250μl)             200元

● 产品简介：

本产品是由λ DNA经HindIII完全酶切而成，适用于琼脂糖凝胶电泳中DNA条带的分析。产品浓度为0.1μg/μl，已含有1×loading buffer，可直接取2-5μl上样，使用方便。8条带的大小分别为125，564，2027，2322，4361，6557，9416，23130bp。

● 储存条件：

  4℃ 贮存（长期贮存置于-20℃）。

●    使用方法和说明：

1.65℃加热5分钟，立即冰浴3分钟，取2-5μl本产品加入到琼脂糖凝胶的加样孔中。

注：根据梳子的厚度和宽度进行上样。每1mm×1mm（厚度×宽度）加样孔上样1μl。窄齿梳子（一般为1mm×2mm）上样2μl；宽齿梳子（一般为1mm×5mm）上样5μl。如果使用厚齿梳子或宽于5mm的梳子，可以适当调整上样量。

2. 建议电泳条件：凝胶浓度为1.0％，凝胶长度10cm，电泳电压4-10v/cm，电泳时间45分钟。

3. 通过EB染色后紫外灯下观察条带。

注：如果使用Goldview等染料就行染色，由于灵敏度比EB低，请酌情增加Marker的上样量。

● 注意事项：

1. λ DNA酶切Marker的末端容易由COS末端结合在一起，电泳前65℃预热5分钟能解开结合的COS末端，得到更清晰的电泳图像。如果不预热，23130bp和4361bp会结合形成27491bp的额外片段，同时电泳后4361bp亮度会明显弱于其他片段。

 3. 请使用新鲜配制的电泳缓冲液和新鲜配制的琼脂糖凝胶进行电泳，以保证Marker良好的分离效果。
