Ultra Low Molecular Weight Protein Marker III

●产品编号及规格：

RTD6125   10T（50μl）   300元

● 储存条件：

  -20℃保存，开封后有效期12个月。

● 产品简介：

本产品包含5种多肽和3种低分子量蛋白质组成，分子量范围为3.4kD-100kD。可以用来判断 SDS-PAGE上多肽和小蛋白的分子量。  

● 使用说明：

第一次收到该产品，室温融化后，彻底混匀，离心快甩将溶液完全收集到管底，根据需要适量分装成小管，-20℃贮存，每次取一小管使用；本产品为即用型，融化后既能使用，不能95℃加热处理。

一. 制胶：

I 配制分离胶

1．按照表一将不同体积的双蒸水、40%PAA（19:1）、凝胶缓冲液和乙二醇加入到小烧杯中混合。

2．加入10%APS和TEMED，立即混匀5-10秒，以使溶液充分混匀。

3．在凝胶模具中迅速灌入适量分离胶溶液，然后在分离胶溶液上轻轻覆盖一层1-3 cm的水层，使凝胶表面保持平整。

4．静置30-60分钟，待分离胶和水层之间出现一个清晰的界面表示凝胶已聚合。

表一  （一块0.75mm mini胶用量）

注：如非必须，不要使用1.0mm和1.5mm的凝胶，尽量使用厚度0.75mm的凝胶，这样会减少电泳后染色和脱色的时间。

II 配制浓缩胶

去除覆盖在分离胶上的水层，用滤纸将残留的水吸去。

1．按照表一将不同体积的双蒸水、40%PAA（29:1）和凝胶缓冲液加入到小烧杯中混合。

2．加入10%过硫酸铵和TEMED，立即混匀5-10秒，以使溶液充分混匀。

3．将梳子插入凝胶内，避免产生气泡。

4．静置30-60分钟装待凝胶聚合

二. 电泳：

1. 取一管分装好的Marker样品，彻底融化，不要加热处理，充分混匀后备用。

2. 电泳前，将10×Tris-Tricine-SDS电泳缓冲液（Cat No：CB010）用蒸馏水稀释成1×缓冲液备用。将电泳槽的内外槽加入1×缓冲液，轻柔拔出梳子，将Marker或蛋白样品（样品已经过2×Tricine上样缓冲液[Cat No：TP050]处理）加入点样孔，根据表二条件进行电泳，至蓝色指示前沿至分离胶3/4位置时即可停止电泳。整个电泳过程大约需要2-3个小时。注：如果电泳时间过短，染色时，指示前沿容易遮挡小于5kd的小肽。

三. 染色

根据常规实验步骤，用配方5和6（表三）进行染色和观察。如果使用配方5进行染色时效果不好或考虑其毒性，请选择本公司的FastBlue蛋白染色液（Cat No：RTD6202），该产品能在5分钟之内完成蛋白的染色，不至于小肽在染色和脱色中从凝胶中脱离，是常规染色液的理想替代品。
