● 儲(chǔ)存條件:
本試劑盒在室溫(15–25℃)干燥條件下,可保存12個(gè)月;更長(zhǎng)時(shí)間的保存可置于2–8℃。(注意:當(dāng)?shù)蜏刭A存時(shí),使用前應(yīng)先將試劑盒內(nèi)的溶液在室溫中放置一段時(shí)間,必要時(shí)可在37℃水浴中預(yù)熱10-20分鐘,以平衡溶液溫度。)
● 產(chǎn)品簡(jiǎn)介:
本試劑盒采用可以高效、專(zhuān)一結(jié)合DNA的硅基質(zhì)材料和獨(dú)特的緩沖液系統(tǒng),從TAE或TBE瓊脂糖凝膠上回收DNA片段,同時(shí)去除蛋白質(zhì)、其它有機(jī)化合物、無(wú)機(jī)鹽離子及寡核苷酸引物等雜質(zhì)??苫厥?00 bp–40 kb大小的片段,回收率大于80%(<100 bp 和>10kb 的DNA片段回收率為30-50 %)。
每個(gè)吸附柱每次最多可吸附的DNA量約為20 μg。
使用本試劑盒回收的DNA可適用于各種常規(guī)操作,包括酶切、PCR、測(cè)序、文庫(kù)篩選、連接和轉(zhuǎn)化等實(shí)驗(yàn)。
● 產(chǎn)品特點(diǎn):
1 溶膠液PN為亮黃色,便于觀察膠是否徹底融化和溶膠體系的pH是否合適。
2 操作快捷,單個(gè)樣品操作少于15分鐘。
注意事項(xiàng):請(qǐng)務(wù)必在使用本試劑盒之前閱讀此注意事項(xiàng)。
1 電泳時(shí)最好換用新鮮的電泳緩沖液,以免影響電泳和回收效果;如有可能,盡量使用TAE系統(tǒng),因?yàn)橛醒芯恐赋鍪褂肨BE系統(tǒng)后,回收產(chǎn)物中的痕量硼酸會(huì)影響后續(xù)的酶切反應(yīng)。
2 切膠時(shí),紫外照射時(shí)間應(yīng)盡量短,以免對(duì)DNA造成損傷;請(qǐng)盡量去除不含目的片段的瓊脂糖凝膠,這將會(huì)對(duì)融膠很有幫助。
3 第一次使用前請(qǐng)按照標(biāo)簽說(shuō)明在漂洗液PW中加入無(wú)水乙醇,并做好標(biāo)記,用完后緊擰瓶蓋。
● 操作步驟:
如非指出,所有離心步驟均為使用臺(tái)式離心機(jī)在室溫下離心。
1 將單一的目的DNA條帶從瓊脂糖凝膠中切下(盡量切除多余部分)放入干凈的離心管中,稱(chēng)取重量。
2 向膠塊中加入3倍體積溶膠液PN (如果凝膠重為100mg,其體積可視為100 μl,則加入300 μl溶膠液),55℃水浴放置10分鐘,其間不斷溫和地上下翻轉(zhuǎn)離心管,以確保膠塊充分溶解。
注意:
① 如果此時(shí)溶膠液變?yōu)榉奂t色,請(qǐng)加入少量3MNaAc pH5.2(一般說(shuō)來(lái),10μl足矣),使溶膠液變?yōu)辄S色再上柱離心。
② 對(duì)于高濃度的凝膠(>2%),按照100mg凝膠加入100μl滅菌水和600μl溶膠液PN的比例加入溶膠液PN。
③ 膠塊完全溶解后最好將膠溶液溫度降至室溫再上柱,因?yàn)槲街谳^高溫度時(shí)結(jié)合DNA的能力較弱。
3 可選步驟:當(dāng)目的片段<500bp時(shí),如想提高回收效率,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分鐘后再進(jìn)行步驟4。當(dāng)目的片段>500bp時(shí),省略此步驟,直接進(jìn)行步驟4。
4 將上一步所得溶液加入到吸附柱CA1中(吸附柱放入收集管中),室溫放置2分鐘,13,000 rpm離心60秒,倒掉收集管中的廢液,將吸附柱重新放入收集管中。
注意:
1 吸附柱CA的有效容積為700μl,如溶膠體系體積大于700μl,分次上柱,保證全部溶液都加到吸附柱中。
2 <100bp和>10kb的片段請(qǐng)?jiān)谑覝胤胖?/b>10分鐘,這將會(huì)提高回收效率。
5 向吸附柱中加入700μl漂洗液PW(使用前請(qǐng)先檢查是否已加入無(wú)水乙醇),13,000 rpm離心60秒,倒掉廢液,將吸附柱重新放入收集管中。
6 向吸附柱中加入500μl漂洗液PW,13,000 rpm離心30-60秒,倒掉廢液。
7 將離心吸附柱CA1放回收集管中,13,000 rpm離心2分鐘,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(zhì)量,進(jìn)而影響下游實(shí)驗(yàn);離心后將吸附柱蓋子打開(kāi),室溫放置2分鐘,這樣將有助于徹底揮發(fā)殘余乙醇。
8 將吸附柱放到一個(gè)干凈離心管中,向吸附膜中間位置懸空滴加適量洗脫緩沖液EB(一般不要少于30μl),室溫放置2分鐘。13,000 rpm離心1分鐘收集DNA溶液。
注意:
1可將洗脫緩沖液EB預(yù)熱到70℃后再加到吸附膜上,這樣可以提高洗脫效率。
2 CA1柱的洗脫體積不應(yīng)少于30 μl,體積過(guò)小將會(huì)降低回收效率。
3洗脫液的pH值對(duì)于洗脫效率有很大影響。若用水做洗脫液應(yīng)保證其pH值在7.0-8.5范圍內(nèi),pH值低于7.0會(huì)降低洗脫效率
