第一次收到該產(chǎn)品,室溫融化后,徹底混勻,離心快甩將溶液完全收集到管底,根據需要適量分裝成小管,-20℃貯存,每次取一小管使用;本產(chǎn)品為即用型,融化后既能使用,不能95℃加熱處理。
一. 制膠:
I 配制分離膠
1.按照表一將不同體積的雙蒸水、40%PAA(19:1)、凝膠緩沖液和乙二醇加入到小燒杯中混合。
2.加入10%APS和TEMED,立即混勻5-10秒,以使溶液充分混勻。
3.在凝膠模具中迅速灌入適量分離膠溶液,然后在分離膠溶液上輕輕覆蓋一層1-3 cm的水層,使凝膠表面保持平整。
4.靜置30-60分鐘,待分離膠和水層之間出現一個(gè)清晰的界面表示凝膠已聚合。
表一 (一塊0.75mm mini膠用量)
| 
 | 分離膠 | 濃縮膠 | 
| 
 | 18%T, 5%C /6.0 ml | 5%T, 3.3%C/2 ml | 
| 40% PAA(19:1) | 2.7 ml | / | 
| 40% PAA (29:1) | / | 0.25 ml | 
| 4×凝膠緩沖液 | 1.5 ml | 0.5 ml | 
| 乙二醇(電泳級) | 1.8 ml | / | 
| ddH2O | / | 1.25 ml | 
| 10%APS | 50-65 μl | 20 μl | 
| TEMED | 6 μl | 2 μl | 
注:如非必須,不要使用1.0mm和1.5mm的凝膠,盡量使用厚度0.75mm的凝膠,這樣會(huì )減少電泳后染色和脫色的時(shí)間。
II 配制濃縮膠
去除覆蓋在分離膠上的水層,用濾紙將殘留的水吸去。
1.按照表一將不同體積的雙蒸水、40%PAA(29:1)和凝膠緩沖液加入到小燒杯中混合。
2.加入10%過(guò)硫酸銨和TEMED,立即混勻5-10秒,以使溶液充分混勻。
3.將梳子插入凝膠內,避免產(chǎn)生氣泡。
4.靜置30-60分鐘裝待凝膠聚合
二. 電泳:
1. 取一管分裝好的Marker樣品,徹底融化,不要加熱處理,充分混勻后備用。
2. 電泳前,將10×Tris-Tricine-SDS電泳緩沖液(Cat No:CB010)用蒸餾水稀釋成1×緩沖液備用。將電泳槽的內外槽加入1×緩沖液,輕柔拔出梳子,將Marker或蛋白樣品(樣品已經(jīng)過(guò)2×Tricine上樣緩沖液[Cat No:TP050]處理)加入點(diǎn)樣孔,根據表二條件進(jìn)行電泳,至藍色指示前沿至分離膠3/4位置時(shí)即可停止電泳。整個(gè)電泳過(guò)程大約需要2-3個(gè)小時(shí)。注:如果電泳時(shí)間過(guò)短,染色時(shí),指示前沿容易遮擋小于5kd的小肽。
表二 多肽電泳條件
| 恒電壓 | 150 V | 
| 起始電流 | 45-55 mA | 
| 結束電流 | 10-15 mA | 
| 電泳時(shí)間 | 2-3小時(shí) | 
三. 染色
根據常規實(shí)驗步驟,用配方5和6(表三)進(jìn)行染色和觀(guān)察。如果使用配方5進(jìn)行染色時(shí)效果不好或考慮其毒性,請選擇本公司的FastBlue蛋白染色液(Cat No:RTD6202),該產(chǎn)品能在5分鐘之內完成蛋白的染色,不至于小肽在染色和脫色中從凝膠中脫離,是常規染色液的理想替代品。
