100 bp DNA Ladder

● 産品編号及規格:

    RTM409-02       100T (2×250μl)  

● 産品簡介:

本産品是由11條帶狀雙鏈DNA組成,适用于瓊脂糖凝膠電(diàn)泳中DNA條帶的分析。本産品為(wèi)即用型産品,已含有1×loading buffer,可根據實驗需要,直接取2-5μl電(diàn)泳,使用方便,電(diàn)泳圖像清晰。 本産品中11條帶為(wèi)10020030040050060070080090010001500bp,其中500bp條帶為(wèi)100ng/5μl,其餘條帶濃度為(wèi)50ng/5μl


● 儲存條件(jiàn):

  4 貯存6個(gè)月(yuè),-20貯存 1年(nián)。

● 使用方法:

1. 取2-5 μl本産品加入到(dào)瓊脂糖凝膠的加樣孔中(每1mm×1mm加樣孔加1μl,如果加樣孔寬于 

5mm,可以适當增加上(shàng)樣量)進行電(diàn)泳。

2. 建議電(diàn)泳條件(jiàn):凝膠濃度為(wèi)1.0%,凝膠長(cháng)度10 cm,電(diàn)泳電(diàn)壓~7 v/cm,電(diàn)泳時間50分鍾+

3. 通(tōng)過核酸染料染色後紫外燈或藍光(guāng)儀下(xià)觀察條帶。

● 注意事(shì)項:

1. 瓊脂糖的質量對DNA的電(diàn)泳有很大影響,電(diàn)泳時請盡量使用質量優等的瓊脂糖。由于PAGE電(diàn)泳的特殊性,該産品不建議用于PAGE電(diàn)泳。

2. 使用與電(diàn)泳緩沖液一(yī)緻的緩沖液融化瓊脂糖,例如使用1×TAE緩沖液電(diàn)泳,需使用1×TAE緩沖液溶膠。

3. 多(duō)次電(diàn)泳後緩沖液電(diàn)導增強,相(xiàng)同電(diàn)壓下(xià)電(diàn)流增大,導緻分辨率降低(dī),并且明顯産熱,嚴重時會(huì)引起凝膠熔化或DNA變性。

4. 推薦使用RealSafe系列染料(貨号:GR002,GR003,GR004)染色。如果使用Goldview或EB等染料進行染色,由于此類染料帶更多(duō)的正電(diàn)荷(染料移動方向與核酸泳動方向相(xiàng)反),随著(zhe)電(diàn)泳時間延長(cháng),染料向大片段聚集,凝膠會(huì)出現陰陽膠現象(染料含量高(gāo)的凝膠紫外下(xià)較亮,含量低(dī)的凝膠紫外下(xià)發暗(àn)),導緻小(xiǎo)分子量DNA顯色很弱或不可見(jiàn)。陰陽膠可以在電(diàn)泳結束後浸泡染色,将膠浸沒在含1 μg /ml EB或Goldview的電(diàn)泳緩沖液中20-25 min,小(xiǎo)分子量DNA會(huì)顯色清楚。更長(cháng)時間浸泡會(huì)因DNA分子擴散而使條帶彌散,小(xiǎo)分子量DNA更易彌散。

5. 紫外照(zhào)射下(xià)EB易分解,使DNA條帶熒光(guāng)變淺。DNA受紫外光(guāng)照(zhào)射形成嘧啶二聚體,不利于待回收片段的下(xià)遊工(gōng)作,因此盡可能(néng)減少紫外照(zhào)射時間。

6. 蔗糖會(huì)結合DNA,降低(dī)其電(diàn)泳遷移率,建議DNA樣品上(shàng)樣使用含甘油的Loading Buffer。

7. 大部分核酸工(gōng)具酶會(huì)結合DNA,降低(dī)其電(diàn)泳遷移率,大分子量DNA尤為(wèi)明顯。
