【PAGE凝膠蛋白/核酸純化】取代Passive elution和電洗脫electro elution 貨號PN-019
Minute™膠體蛋白質及核酸萃取套組 | Minute™ Protein/Nucleic Acid Extraction Kit from Gels| 貨號PN-019

產品介紹: 聚丙烯酰胺/瓊脂糖凝膠(polyacrylamide/agarose gels)中提取蛋白質和/或核酸的最常見的方法,為被動elution(Passive elution)和電洗脫(electro elution)兩種。通過Passive elution被動洗脫的蛋白質提取通常需要overnight incubation 。Elution蛋白被顯著稀釋並需要再進一步濃縮。通過(electro elution)電泳elution的蛋白質提取比被動elution更快(30分鐘至2小時),但對於較大蛋白質(> 70Kda)less effectively較不有效,且需 特殊elution裝置device。電緩衝液通常含有可能干擾下游應用的濃度的洗滌劑和其它化學品。Invent提供了一個快速,無儀器的蛋白質/核酸提取試劑盒。蛋白質/核酸可以在<10分鐘內以高產率從polyacrylamide/agarose gels凝膠中提取。洗脫緩衝液可以是含洗滌劑的緩衝液或純水,取決於凝膠染色的方法。Elution的體積在10至200μL之間。多個凝膠塊可以在單個管中處理,並且最終蛋白質濃度可相對提高。提取的蛋白質可用於MALD-MS分析、動物免疫、蛋白質 – 蛋白質相互作用和蛋白質 – 核酸相互作用研究等。核酸可用於PCR,Cloning和sequencing等。

Minute™膠體蛋白質及核酸萃取套組操作手冊
A.從聚丙烯酰胺凝膠中提取蛋白質:
1.通過SDS-PAGE或2-D凝膠分離蛋白質樣品後,凝膠可以用a染色陽性染色法如標准考馬斯藍染色或陰性染色方法(見參考文獻)。將凝膠去染色以顯示感興趣的蛋白質條帶。
如果凝膠用考馬斯藍染色染色,用ddH2O沖洗凝膠至少3次。After separation of protein samples by SDS-PAGE or 2-D gel, the gel can be stained by a positive staining method such as standard Coomassie blue staining or a negative staining method (see references bellow). The gel is de-stained to reveal protein band(s) of interest. Rinse the gel with ddH2O at least 3 times if the gel is stained with Coomassie blue staining.
2.用刀片從凝膠中切出感興趣的條帶,並去除過多的凝膠。去掉通過與濾紙接觸而與凝膠相關的過量液體放置1-2切除的凝膠在200μl管的底部提供的碎片(該管可以容納多個碎片切除凝膠)。Cut the band of interest out of the gel with a blade and trim away excessive gel. Remove excessive liquid associated with the gel by touching with filter paper Place 1-2 excised gel
pieces at the bottom of 200 µl tube provided ( the tube can accommodate multiple pieces of excised gels).
3.將提取粉末(約為凝膠體積的1/4至1/3)加入管底部的凝膠中使用杵的扁平端。將您選擇的洗脫緩衝液(見下文)添加到同一管中(20μl/片凝膠)。將鋒利的杵叉插入管底並扭轉管子反復來回以減少凝膠到漿液。也可以用凝膠打孔反覆研杵以將其減少為細漿(大約需要1-2分鐘,杵可以重複使用,清潔只需用蒸餾水沖洗並用紙巾擦乾)。將管加入20-50μl/凝膠片洗脫緩衝液至管中,確保凝膠漿液由洗脫緩衝液覆蓋。蓋上試管,在PCR機中於94℃孵育5-10分鐘,將管短暫渦旋並繼續孵育另外5-10分鐘。更長的孵化期增加蛋白質產量。加蓋的管也可以在4℃下放置過夜。Add extraction powder (about 1/4 to 1/3 the volume of the gel) to the gel at bottom of the tube using the flat end of the pestle. Add elution buffer of your choice (see below) to the same tube (20 µl/piece of gel). Insert the sharp fork of pestle to the bottom of the tube and twist the tube back and forth repeatedly to reduce the gel to slurry. You can also punch the gel with the pestle repeatedly to reduce it to a fine slurry (it takes about 1-2 min, the pestle is reusable, for cleaning simply rinse with distilled water and dry it with paper towel). While the pestle still in the tube add 20-50 µl/gel piece elution buffer to the tube and make sure the gel slurry is covered by elution buffer. Cap the tube and incubate at 94oC in a PCR machine for 5-10 min, vortex the tube briefly and continue to incubate for another 5-10 min. Longer incubation will increase protein yield. The capped tube can also be left at 4oC overnight.
4.打開200μl管的蓋子和收集管的蓋子。用刀片修剪帽子還是一把剪刀。將200μl管的開口端插入濾筒並離心在微型離心機中以最高速度運行2分鐘。丟棄過濾器並將洗脫的蛋白質保存在收集中管。
Open the cap of the 200 µl tube and the cap of collection tube. Trim the caps off with a blade or a pair of scissors. Insert the opening end of 200 µl tube to the filter cartridge and centrifuge
in a microfuge at top speed for 2 min. Discard the filter and save eluted protein in collection tube.
B.從瓊脂糖凝膠中提取核酸
1.用刀片從凝膠中切下感興趣的條帶,並去除過多的凝膠。
2.將凝膠片放入提供的200μl管中。向管中加入萃取粉(約1/4至約 1/3體積的凝膠,見上文)。
3.如上所述,用研棒研磨凝膠以將凝膠還原成漿液。修剪掉帽子200μl管和收集管。將200μl管的開口端插入濾芯並以最高速度離心1分鐘。丟棄過濾器並保存洗脫的核酸
收集管。
