考马斯亮蓝染色套装使用说明

考马斯亮蓝染色套装使用说明货号:P1305保存:室温保存,至少一年有效。
规格:100ml+500ml产品简介:本考马斯亮蓝染色套装(Commassie Blue Staining Kit)采用了最经典的考马斯亮蓝染色和脱色方法,以考马斯亮蓝G-250为染料,可用于SDS-PAGE或非变性PAGE等蛋白电泳凝胶的常规染色和脱色,或Western 转膜后PAGE胶上残余蛋白的检测。
产品内容:考马斯亮蓝染色液100ml考马斯亮蓝脱色液500ml说明书1份使用方法:1、电泳结束后,取凝胶放入适量考马斯亮蓝染色液中(至少5倍胶体积),确保染色液可以充分覆盖凝胶。
2、将凝胶置于摇床上缓慢摇动,室温染色至少2小时,低丰度蛋白染色需4小时以上。
3、染色结束后移除染色液,染色液通常可重复利用2-3次,但染色效果会略有影响。
4、将凝胶浸泡于和染色液等量体积的脱色液中,摇床上脱色4-8小时,期间更换3-5次脱色液。
注意事项:1.染色时间4小时以上效果最佳。
2.脱色可根据目的蛋白丰度和脱色效果随时终止,或延长脱色时间。
3.脱色越彻底,检测的蛋白量越低,脱色24小时一般可以检测出0.1ug蛋白量。
4.脱色后,将凝胶保存在水中,拍照或扫描保存图像。
或制成干胶保存。

蛋白标准品(Marker)知识汇总

蛋白Marker可分为:一、未预染的Marker即宽分子量蛋白标准、高分子量蛋白标准以及低分子量蛋白标准;二、预染的Marker即单色预染和多色预染。
在western blot 过程中,分子量Marker就像个螺丝钉一样没虽然是个小细节,然而就是这样一个小细节对实验结果有着不可忽视的作用。
这个Western Blot 参照家族的一员的作用主要是用来指示蛋白条带所对应的分子量大小,只有标准量精确无误了,实验结果才有说服力,除此之外,蛋白标准还有表示转移成功或者蛋白在凝胶上的电泳程度等等的作用,所以选择正确的蛋白Marker也是western blot实验成功的必要条件之一。
总体来说,蛋白分子量标准可以分成未染蛋白分子量标准、预染蛋白分子量标准二个级别。
以下是关于蛋白分子量标准的小叙:一. 未染色(pre mixed)蛋白分子量标准未染色的蛋白分子量标准是最简单,也是最准确的一种。
由于没有附带染料分子或者是标记分子,所示大小正好是蛋白原本的大小,是精确判断蛋白大小必须的。
现在的Marker多数都选用预混和的Marker,方便不同大小的蛋白比较。
预混的Marker通常有几条带加倍浓度作为指示,因为混合的条带越多,越不好记,谁知道哪条是那条!数到眼都花了。
所以当看到特别浓的那几条标志带就记得是哪里了。
不过要记得,小带通常都不那么容易看清楚的。
在选择上来说,当然是选择其中至少有一条条带和自己的目的蛋白大小相近的最好,越近越好。
如果你的蛋白不幸在两条跨度较大Marker条带之间,选别的Marker吧。
预混的Marker 使用上不如预染Marker(pre-stained)好用,因为电泳过程中完全看不到,要和目标蛋白一起等到最后染色才“开蛊”,无法对实验起预示参照作用。
完全属于“后知后觉”型的,当然还是比“不知不觉”不做对照的要好。
①宽分子量蛋白标准如果从实验室总体考虑的,就选范围尽量宽,条带分布比较均匀的,这样你的蛋白无论在哪个区间都容易判断,避免正好落在一段空白区的危险。

λ-Hin dⅢdigest DNA Marker使 用 说 明 书Code No.:D3403A●包 装 量:50 µg(500 µl×2支;内含1×Loading Buffer)●浓 度:50 ng/µl●制品说明:λ-Hin d III digest DNA Marker是由Bacteriophage λc I857Sam7 DNA用Hin d III酶切反应后配制而成的。
本制品浓度为50ng/µl,内含1×Loading Buffer,可根据实验需要,每次取5µl~20 µl电泳,使用方便,电泳图像清晰。
●保存温度:-20℃●使用注意:1.λDNA digest DNA Markers的原始末端之间经常由COS末端结合在一起,在电泳前进行热处理(60℃, 5分钟),能使Marker的电泳图像变得更为清晰。
以λ-Hin d III digest DNA Marker为例,原始末端之间的COS末端的结合,影响23,130 bp和4,361 bp的DNA条带。
如果电泳以后的图像中的4,361 bp的DNA条带亮度低于比其小的DNA片段时,那说明COS末端的结合情况比较严重。
2. 电泳时的加样孔宽度小于6 mm时,每次取5µl制品电泳便可得到清晰条带。
如果加样孔增宽,须适当增加Marker制品的加样量。
3.对DNA电泳而言,Agarose的纯度对DNA条带的清晰度影响很大。
因此,电泳时应尽量选用质量好的Agarose。
