● 儲(chu)存條件:
本試劑盒在(zai)(zai)室(shi)溫(wen)(wen)(wen)(15–25℃)干燥條件下,可保存12個月;更長時(shi)(shi)間的保存可置于2–8℃。(注意:當低溫(wen)(wen)(wen)貯存時(shi)(shi),使用前應先將試劑盒內的溶液在(zai)(zai)室(shi)溫(wen)(wen)(wen)中放置一段時(shi)(shi)間,必(bi)要時(shi)(shi)可在(zai)(zai)37℃水浴中預熱10-20分鐘(zhong),以平衡(heng)溶液溫(wen)(wen)(wen)度。)
● 產(chan)品(pin)簡介(jie):
本試劑盒采用可以高(gao)效(xiao)、專一結合DNA的(de)硅基質材料和獨特的(de)緩沖液系統(tong),從TAE或TBE瓊脂糖(tang)凝膠(jiao)上(shang)回收DNA片段,同時(shi)去除蛋白質、其它(ta)有(you)機(ji)化合物、無機(ji)鹽(yan)離子(zi)及寡核苷(gan)酸引物等雜質。可回收100 bp–40 kb大小(xiao)的(de)片段,回收率大于80%(<100 bp 和>10kb 的(de)DNA片段回收率為(wei)30-50 %)。
每(mei)個吸附柱每(mei)次最多可吸附的DNA量約為20
μg。
使用(yong)本試劑(ji)盒(he)回收的DNA可適用(yong)于各種(zhong)常規操作,包括酶切、PCR、測序、文庫篩選、連接(jie)和轉化等(deng)實(shi)驗。
● 產品(pin)特(te)點:
1 溶(rong)膠液PN為亮黃色,便于觀(guan)察(cha)膠是否徹底融化和溶(rong)膠體系的pH是否合(he)適。
2 操作快捷,單個樣品操作少于(yu)15分鐘。
注意事項:請務必在使用本試(shi)劑盒之(zhi)前閱讀(du)此注意(yi)事項。
1 電(dian)(dian)泳(yong)時(shi)最好換(huan)用(yong)新鮮的(de)電(dian)(dian)泳(yong)緩沖液,以免影(ying)(ying)響電(dian)(dian)泳(yong)和回收效果(guo);如有可能,盡量(liang)使用(yong)TAE系(xi)統,因(yin)為(wei)有研究指出(chu)使用(yong)TBE系(xi)統后,回收產物中的(de)痕量(liang)硼酸會(hui)影(ying)(ying)響后續的(de)酶切反應。
2 切膠(jiao)時,紫外照射時間應盡量短,以免對(dui)DNA造成損傷;請(qing)盡(jin)量去(qu)除(chu)不含目的(de)片段(duan)的(de)瓊脂(zhi)糖凝膠,這(zhe)將會對融膠很(hen)有幫助。
3 第(di)一次(ci)使用(yong)前請按照(zhao)標(biao)簽(qian)說明(ming)在漂洗液PW中加(jia)入無水乙醇(chun),并(bing)做好(hao)標(biao)記,用(yong)完后緊(jin)擰瓶(ping)蓋。
● 操作步驟:
如非指出(chu),所有離(li)心(xin)步驟均為使用(yong)臺(tai)式離(li)心(xin)機在室溫下離(li)心(xin)。
1 將(jiang)單一的目(mu)的DNA條帶(dai)從瓊脂(zhi)糖凝膠(jiao)中(zhong)切(qie)下(xia)(盡(jin)量切(qie)除多(duo)余(yu)部分)放入干凈(jing)的離心管中(zhong),稱取重量。
2 向(xiang)膠(jiao)塊中加(jia)(jia)入(ru)3倍體(ti)(ti)積(ji)溶(rong)膠(jiao)液PN (如果凝膠(jiao)重為100mg,其體(ti)(ti)積(ji)可視為100 μl,則(ze)加(jia)(jia)入(ru)300 μl溶(rong)膠(jiao)液),55℃水(shui)浴放置10分鐘,其間不(bu)斷溫和地上(shang)下翻轉離(li)心管,以確(que)保膠(jiao)塊充分溶(rong)解。
注意:
① 如果(guo)此時(shi)溶(rong)膠液變為粉紅色(se),請(qing)加(jia)入(ru)少量3MNaAc pH5.2(一般說(shuo)來,10μl足矣(yi)),使溶(rong)膠液變為黃色(se)再(zai)上柱離(li)心。
② 對于高濃度的凝膠(>2%),按照(zhao)100mg凝膠加入(ru)100μl滅菌(jun)水和600μl溶膠液PN的比(bi)例加入(ru)溶膠液PN。
③ 膠(jiao)塊(kuai)完全(quan)溶(rong)解(jie)后最好將膠(jiao)溶(rong)液溫度降至室(shi)溫再上柱(zhu),因為(wei)吸附(fu)柱(zhu)在較高溫度時結合(he)DNA的(de)能力(li)較弱。
3
可(ke)選步驟:當目的片段<500bp時,如想提高回收效率,向溶膠體系(xi)種(zhong)加入1/3溶膠液PN體積(ji)的異(yi)丙醇(如使用300μl溶膠液,則加入100μl異丙醇(chun)),混勻,55℃溫浴(yu)1分鐘后再進(jin)行步(bu)驟(zou)4。當目(mu)的片(pian)段>500bp時,省(sheng)略(lve)此步(bu)驟(zou),直(zhi)接進(jin)行步(bu)驟(zou)4。
4 將上一步所得溶液加入到吸(xi)附柱(zhu)(zhu)CA1中(吸(xi)附柱(zhu)(zhu)放入收集管(guan)中),室溫(wen)放置2分鐘,13,000
rpm離心60秒,倒掉收集管(guan)中的廢(fei)液,將吸(xi)附柱(zhu)(zhu)重新(xin)放入收集管(guan)中。
注(zhu)意(yi):
1 吸(xi)附柱(zhu)CA的有效容積(ji)為700μl,如溶膠體(ti)系體(ti)積大于700μl,分(fen)次上柱,保(bao)證全部溶液都(dou)加到吸附柱中(zhong)。
2
<100bp和>10kb的片(pian)段(duan)請在室溫放置(zhi)10分(fen)鐘,這將會(hui)提高回(hui)收效(xiao)率(lv)。
5 向吸附柱中加入700μl漂洗(xi)液(ye)PW(使用前(qian)請先(xian)檢查是否(fou)已(yi)加入無水乙醇),13,000 rpm離(li)心60秒(miao),倒掉廢液,將(jiang)吸附(fu)柱重新放(fang)入(ru)收集管(guan)中。
6 向吸(xi)附柱中加入500μl漂(piao)洗液(ye)(ye)PW,13,000
rpm離心30-60秒,倒掉廢液(ye)(ye)。
7 將離心吸附柱(zhu)CA1放回收集管中(zhong),13,000 rpm離心2分鐘,盡量除去漂洗液。
注意:此(ci)步必不可少(shao)!如果漂洗液有殘留會影響(xiang)回收(shou)效率和DNA質量,進(jin)而影響下游實驗;離心后將吸附柱蓋子打開,室溫放(fang)置2分鐘,這(zhe)樣(yang)將有(you)助于徹底(di)揮發(fa)殘余乙醇(chun)。
8 將吸(xi)附柱放到(dao)一(yi)個干凈離心管中(zhong),向吸(xi)附膜中(zhong)間(jian)位置懸空(kong)滴加適量(liang)洗脫緩沖液EB(一(yi)般不要少于30μl),室溫放置2分(fen)鐘(zhong)。13,000 rpm離心1分(fen)鐘(zhong)收(shou)集DNA溶液。
注意:
1可將洗脫緩沖(chong)液EB預熱到70℃后再加到吸附膜上,這樣可以提(ti)高(gao)洗脫(tuo)效率。
2 CA1柱的洗(xi)脫體積不應少于30
μl,體積過小(xiao)將(jiang)會降低回收效率。
3洗脫液的pH值(zhi)對于洗脫效率(lv)有(you)很大影響(xiang)。若用(yong)水做洗脫液應保(bao)證其pH值(zhi)在7.0-8.5范圍內,pH值低(di)于(yu)7.0會降低洗(xi)脫效率(lv)
9 DNA產(chan)物-20℃保存(cun)。
