● 產品簡介:
10×Tris-醋(cu)酸-SDS電(dian)(dian)泳(yong)緩沖(chong)液是(shi)可以用(yong)(yong)于Tris-醋(cu)酸系統蛋(dan)白凝膠(jiao)電(dian)(dian)泳(yong)的電(dian)(dian)泳(yong)緩沖(chong)液,用(yong)(yong)于蛋(dan)白變性電(dian)(dian)泳(yong)。本溶液為10×濃縮液,使用(yong)(yong)前稀(xi)釋成(cheng)1×即用(yong)(yong)型緩沖(chong)液使用(yong)(yong)。1×即用(yong)(yong)型Tris-醋(cu)酸-SDS電(dian)(dian)泳(yong)緩沖(chong)液組份(fen)濃度為:50 mM Tris,50
mM Tricine,0.1% SDS,~pH8.2。
對于還原樣品電(dian)泳(yong),1×即用(yong)型電(dian)泳(yong)緩沖液要添(tian)加(jia)400×抗(kang)氧化劑(貨(huo)號:TA1510)后使用(yong);非還原樣品電(dian)泳(yong),不需要添(tian)加(jia)抗(kang)氧化劑。
● 貯存和效期及運輸:
4℃保存,有效期1年,常溫運輸。

注(zhu):配制(zhi)好的(de)1×Tris-醋(cu)酸-SDS電(dian)(dian)泳(yong)緩沖(chong)(chong)液(ye)盡量現用(yong)(yong)現配。回收(shou)的(de)電(dian)(dian)泳(yong)液(ye)可以用(yong)(yong)于外槽(cao)緩沖(chong)(chong)液(ye)重復(fu)使用(yong)(yong)1-2次,內槽(cao)緩沖(chong)(chong)液(ye)每次使用(yong)(yong)新鮮配制(zhi)的(de)電(dian)(dian)泳(yong)液(ye)。本(ben)電(dian)(dian)泳(yong)緩沖(chong)(chong)液(ye)含(han)有SDS,不(bu)適用(yong)(yong)于非變(bian)性凝膠電(dian)(dian)泳(yong)。
2. 電泳:
外槽(cao)緩(huan)(huan)沖(chong)液:取800 ml 1×電泳緩(huan)(huan)沖(chong)液用于外槽(cao)緩(huan)(huan)沖(chong)液。
內槽(cao)緩沖(chong)液:對于還原樣(yang)品電(dian)泳(yong)(yong),200 ml 1×電(dian)泳(yong)(yong)緩沖(chong)液中(zhong)(zhong)加(jia)0.5 ml 400×抗氧化(hua)劑(貨號:TA1510),混合均勻(yun)后用于內槽(cao)緩沖(chong)液。對于非還原樣(yang)品電(dian)泳(yong)(yong),直接在內槽(cao)中(zhong)(zhong)加(jia)入1×電(dian)泳(yong)(yong)緩沖(chong)液,不要添加(jia)400×抗氧化(hua)劑。
注:Tris-醋酸(suan)系統凝膠pH為中(zhong)性,在(zai)中(zhong)性pH條件下蛋(dan)白樣品中(zhong)的(de)還(huan)原劑(ji)(ji)(如(ru)DTT或BME)不能有效(xiao)隨蛋(dan)白樣品移動,還(huan)原劑(ji)(ji)會聚(ju)集在(zai)凝膠上沿。內槽緩沖液中(zhong)加入抗氧化(hua)劑(ji)(ji)后,抗氧化(hua)劑(ji)(ji)可(ke)以隨著樣品一起移動,保證(zheng)蛋(dan)白在(zai)整(zheng)個(ge)電泳過程中(zhong)保持還(huan)原狀態,得到更加稅利(li)的(de)條帶。
