● 使用說(shuō)明：

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(jù)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(xiàn)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）

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(nèi)，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(nèi)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(jù)表二條件進(jìn)行電泳，至藍(lán)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

三. 染色

根據(jù)常規(guī)實(shí)驗(yàn)步驟，用配方5和6（表三）進(jìn)行染色和觀察。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(qǐng)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(nèi)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(guī)染色液的理想替代品。
