超低分(fēn)子量蛋白(bái)質Marker III3.4-100kD

Ultra Low Molecular Weight Protein Marker III

産品編号及規格:

RTD6125   10T50μl)   300元

儲存條件(jiàn):

  -20保存,開封後有效期12個月。

産品簡介:

本産品包含5種多肽和3種低分(fēn)子量蛋白(bái)質組成,分(fēn)子量範圍爲3.4kD-100kD。可(kě)以用來(lái)判斷 SDS-PAGE上多肽和小蛋白(bái)的分(fēn)子量。  


使用說(shuō)明:

第一次收到該産品,室溫融化後,徹底混勻,離(lí)心快(kuài)甩将溶液完全收集到管底,根據需要适量分(fēn)裝成小管,-20℃貯存,每次取一小管使用;本産品爲即用型,融化後既能使用,不能95加熱(rè)處理(lǐ)

. 制膠:

I 配制分(fēn)離(lí)膠

1.按照(zhào)表一将不同體(tǐ)積的雙蒸水、40%PAA19:1)、凝膠緩沖液和乙二醇加入到小燒杯中混合。

2.加入10%APSTEMED,立即混勻5-10秒,以使溶液充分(fēn)混勻。

3.在凝膠模具中迅速灌入适量分(fēn)離(lí)膠溶液,然後在分(fēn)離(lí)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(jìng)置30-60分(fēn)鍾,待分(fēn)離(lí)膠和水層之間出現一個清晰的界面表示凝膠已聚合。

注:如(rú)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,這樣會減少電泳後染色和脫色的時間。

II 配制濃縮膠

去(qù)除覆蓋在分(fēn)離(lí)膠上的水層,用濾紙将殘留的水吸去(qù)。

1.按照(zhào)表一将不同體(tǐ)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%過硫酸铵和TEMED,立即混勻5-10秒,以使溶液充分(fēn)混勻。

3.将梳子插入凝膠内,避免産生(shēng)氣泡。

4.靜(jìng)置30-60分(fēn)鍾裝待凝膠聚合

. 電泳:

1. 取一管分(fēn)裝好的Marker樣品,徹底融化,不要加熱(rè)處理(lǐ),充分(fēn)混勻後備用。

2. 電泳前,将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。将電泳槽的内外槽加入1×緩沖液,輕柔拔出梳子,将Marker或蛋白(bái)樣品(樣品已經過2×Tricine上樣緩沖液[Cat No:TP050]處理(lǐ))加入點樣孔,根據表二條件(jiàn)進行電泳,至藍色指示前沿至分(fēn)離(lí)膠3/4位置時即可(kě)停止電泳。整個電泳過程大(dà)約需要2-3個小時。注:如(rú)果電泳時間過短(duǎn),染色時,指示前沿容易遮擋小于5kd的小肽。

. 染色

根據常規實驗步驟,用配方5和6(表三)進行染色和觀察。如(rú)果使用配方5進行染色時效果不好或考慮其毒性,請(qǐng)選擇本公司的FastBlue蛋白(bái)染色液(Cat No:RTD6202),該産品能在5分(fēn)鍾之内完成蛋白(bái)的染色,不至于小肽在染色和脫色中從(cóng)凝膠中脫離(lí),是常規染色液的理(lǐ)想替代品。
