● 儲存條件(jiàn):
本試劑盒在室溫(15–25℃)幹燥條件(jiàn)下(xià),可保存12個(gè)月(yuè);更長(cháng)時間的保存可置于2–8℃。(注意:當低(dī)溫貯存時,使用前應先将試劑盒内的溶液在室溫中放(fàng)置一(yī)段時間,必要時可在37℃水(shuǐ)浴中預熱10-20分鍾,以平衡溶液溫度。)
● 産品簡介:
本試劑盒采用可以高(gāo)效、專一(yī)結合DNA的矽基質材料和獨特的緩沖液系統,從(cóng)TAE或TBE瓊脂糖凝膠上(shàng)回收DNA片段,同時去除蛋白(bái)質、其它有機(jī)化合物(wù)、無機(jī)鹽離子及寡核苷酸引物(wù)等雜(zá)質。可回收100 bp–40 kb大小(xiǎo)的片段,回收率大于80%(<100 bp 和>10kb 的DNA片段回收率為(wèi)30-50 %)。
每個(gè)吸附柱每次最多(duō)可吸附的DNA量約為(wèi)20
μg。
使用本試劑盒回收的DNA可适用于各種常規操作,包括酶切、PCR、測序、文庫篩選、連接和轉化等實驗。
● 産品特點:
1 溶膠液PN為(wèi)亮黃色,便于觀察膠是否徹底融化和溶膠體系的pH是否合适。
2 操作快捷,單個(gè)樣品操作少于15分鍾。
注意事(shì)項:請務必在使用本試劑盒之前閱讀(dú)此注意事(shì)項。
1 電(diàn)泳時最好換用新鮮的電(diàn)泳緩沖液,以免影響電(diàn)泳和回收效果;如有可能(néng),盡量使用TAE系統,因為(wèi)有研究指出使用TBE系統後,回收産物(wù)中的痕量硼酸會(huì)影響後續的酶切反應。
2 切膠時,紫外照(zhào)射時間應盡量短,以免對DNA造成損傷;請盡量去除不含目的片段的瓊脂糖凝膠,這将會(huì)對融膠很有幫助。
3 第一(yī)次使用前請按照(zhào)标簽說明在漂洗液PW中加入無水(shuǐ)乙醇,并做好标記,用完後緊擰瓶蓋。
● 操作步驟:
如非指出,所有離心步驟均為(wèi)使用台式離心機(jī)在室溫下(xià)離心。
1 将單一(yī)的目的DNA條帶從(cóng)瓊脂糖凝膠中切下(xià)(盡量切除多(duō)餘部分)放(fàng)入幹淨的離心管中,稱取重量。
2 向膠塊中加入3倍體積溶膠液PN (如果凝膠重為(wèi)100mg,其體積可視為(wèi)100 μl,則加入300 μl溶膠液),55℃水(shuǐ)浴放(fàng)置10分鍾,其間不斷溫和地上(shàng)下(xià)翻轉離心管,以确保膠塊充分溶解。
注意:
① 如果此時溶膠液變為(wèi)粉紅(hóng)色,請加入少量3MNaAc pH5.2(一(yī)般說來,10μl足矣),使溶膠液變為(wèi)黃色再上(shàng)柱離心。
② 對于高(gāo)濃度的凝膠(>2%),按照(zhào)100mg凝膠加入100μl滅菌水(shuǐ)和600μl溶膠液PN的比例加入溶膠液PN。
③ 膠塊完全溶解後最好将膠溶液溫度降至室溫再上(shàng)柱,因為(wèi)吸附柱在較高(gāo)溫度時結合DNA的能(néng)力較弱。
3
可選步驟:當目的片段<500bp時,如想提高(gāo)回收效率,向溶膠體系種加入1/3溶膠液PN體積的異丙醇(如使用300μl溶膠液,則加入100μl異丙醇),混勻,55℃溫浴1分鍾後再進行步驟4。當目的片段>500bp時,省略此步驟,直接進行步驟4。
4 将上(shàng)一(yī)步所得溶液加入到(dào)吸附柱CA1中(吸附柱放(fàng)入收集管中),室溫放(fàng)置2分鍾,13,000
rpm離心60秒(miǎo),倒掉收集管中的廢液,将吸附柱重新放(fàng)入收集管中。
注意:
1 吸附柱CA的有效容積為(wèi)700μl,如溶膠體系體積大于700μl,分次上(shàng)柱,保證全部溶液都加到(dào)吸附柱中。
2
<100bp和>10kb的片段請在室溫放(fàng)置10分鍾,這将會(huì)提高(gāo)回收效率。
5 向吸附柱中加入700μl漂洗液PW(使用前請先檢查是否已加入無水(shuǐ)乙醇),13,000 rpm離心60秒(miǎo),倒掉廢液,将吸附柱重新放(fàng)入收集管中。
6 向吸附柱中加入500μl漂洗液PW,13,000
rpm離心30-60秒(miǎo),倒掉廢液。
7 将離心吸附柱CA1放(fàng)回收集管中,13,000 rpm離心2分鍾,盡量除去漂洗液。
注意:此步必不可少!如果漂洗液有殘留會(huì)影響回收效率和DNA質量,進而影響下(xià)遊實驗;離心後将吸附柱蓋子打開(kāi),室溫放(fàng)置2分鍾,這樣将有助于徹底揮發殘餘乙醇。
8 将吸附柱放(fàng)到(dào)一(yī)個(gè)幹淨離心管中,向吸附膜中間位置懸空滴加适量洗脫緩沖液EB(一(yī)般不要少于30μl),室溫放(fàng)置2分鍾。13,000 rpm離心1分鍾收集DNA溶液。
注意:
1可将洗脫緩沖液EB預熱到(dào)70℃後再加到(dào)吸附膜上(shàng),這樣可以提高(gāo)洗脫效率。
2 CA1柱的洗脫體積不應少于30
μl,體積過小(xiǎo)将會(huì)降低(dī)回收效率。
3洗脫液的pH值對于洗脫效率有很大影響。若用水(shuǐ)做洗脫液應保證其pH值在7.0-8.5範圍内,pH值低(dī)于7.0會(huì)降低(dī)洗脫效率
9 DNA産物(wù)-20℃保存。
