● 産品簡介:
彩虹預染超低分(fēn)子量蛋白(bái)質Marker可(kě)以直接觀察蛋白(bái)電泳及清晰判斷Western Blotting的轉膜效果。本産品包含3種多肽和3種低分(fēn)子量蛋白(bái)質組成,分(fēn)子量範圍爲1.2kD-45kD,分(fēn)子量大(dà)小爲 1.2kD,4.6kD,10kD,16kD,27kD,45kD (注:蛋白(bái)大(dà)小已在18%Tricine-SDS-PAGE中用非預染蛋白(bái)Marker标定過。
● 使用說(shuō)明:
第一次收到該産品,常溫融化後,徹底混勻,離(lí)心快(kuài)甩将溶液完全收集到管底。
一. 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% PAA(19:1)、4×凝膠緩沖液(貨号:GB010)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(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
cm的無水乙醇,使凝膠表面保持平整。
4.靜(jìng)置15-30分(fēn)鍾,待分(fēn)離(lí)膠和乙醇層之間出現一個清晰的界面表示凝膠已聚合。

II 配制濃縮膠
去(qù)除覆蓋在分(fēn)離(lí)膠上的乙醇層,用濾紙将殘留乙醇吸去(qù)。
1.按照(zhào)表一将不同體(tǐ)積的雙蒸水、40%PAA(29:1)和4×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
二. 電泳:
1. 取Marker樣品,充分(fēn)混勻後備用。不要加熱(rè)處理(lǐ)。
2. 電泳前,将10×陽極緩沖液(Cat No:AB080)和10×陰極緩沖液(Cat No:CB010)用蒸餾水稀釋成1×緩沖液備用。将電泳槽的外槽加入1×陽極緩沖液,内槽加入1×陰極緩沖液,輕柔拔出梳子,将Marker或蛋白(bái)樣品(已經過2×Tricine上樣緩沖液[Cat No:TP050]處理(lǐ))加入點樣孔,參考下表進行電泳,至每條帶都(dōu)清晰可(kě)見(jiàn)時停止電泳。整個電泳過程大(dà)約需要2-3個小時。

三. 染色
根據常規實驗步驟,用配方6和7(表三)進行染色和觀察。如(rú)果使用配方6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(貨号:RTD6202),該産品除具有染色快(kuài),無毒,靈敏性高等特點外,還(hái)能對小肽在染色中起到固定作(zuò)用,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。
