儲(chǔ)存條件和效期:

本試劑盒在室溫(25℃左右)干燥條件下,可保存1年。緩沖液R2和R3可能有沉淀產(chǎn)生,若溶液產(chǎn)生沉淀,應(yīng)在使用前置于37℃下溶解沉淀至溶液澄清后再使用。

產(chǎn)品簡(jiǎn)介:

土壤樣品存在大量的抑制因子如腐殖酸、金屬離子等,而純化的DNA 中只要有這些微量物質(zhì)的存在,都會(huì)影響到PCR等酶促反應(yīng)。本公司的土壤試劑盒采用獨(dú)特的腐殖酸去除液(緩沖液R2)能夠有效去除腐殖酸;吸附柱CG能能有效去除金屬等抑制因子,提純得到的基因組DNA可直接用于PCR 反應(yīng),酶切或定量實(shí)驗(yàn)。

準(zhǔn)備工作:

1. 準(zhǔn)備55℃,70℃水浴;無(wú)水乙醇;異丙醇;制冰機(jī);1.5ml離心管;2ml離心管

2. 按照標(biāo)簽所示在漂洗緩沖液WB1和漂洗緩沖液PW中加入無(wú)水乙醇;緩沖液R5中加入異丙醇,混勻后蓋緊瓶蓋后室溫貯存?zhèn)溆谩?

3. 每次使用前請(qǐng)檢查緩沖液R2,緩沖液R3是否有沉淀生成,如果出現(xiàn)沉淀,37℃溫浴至沉淀溶解后再使用。

標(biāo)準(zhǔn)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. 稱(chēng)0.3-0.5 g土壤置于2ml離心管中,加入0.4gGlass Beads,再加入700 μl 緩沖液R1與100 μl 緩沖液R2。渦旋器高速震蕩3-5min。

注意:對(duì)含水量豐富的樣品,可以預(yù)先離心除去部分水分后再稱(chēng)取樣品。緩沖液R2是腐殖酸去除劑,100μl對(duì)大部分樣品來(lái)說(shuō)足以有效除去腐殖酸等抑制因子。對(duì)一些腐殖酸含量特別豐富的土壤, 緩沖液R2的量可以適當(dāng)增加,但不能超過(guò)250μl,否則會(huì)嚴(yán)重影響DNA的得率。

2. 加入100 μl 緩沖液R3(R3如有沉淀37℃水浴完全溶解后再用),渦旋混勻。70℃水浴處理10min。期間振蕩幾次。注意:如果要純化革蘭氏陽(yáng)性菌的DNA,請(qǐng)?jiān)?span>70℃處理完后,再90℃水浴處理2min

3. 12000 rpm(~13,000g)離心1分鐘,取600μl上清到1.5ml離心管中,加入180 μl 緩沖液R4混勻。

注:轉(zhuǎn)移上清時(shí)確保不要吸取到沉淀,轉(zhuǎn)移的上清量最好不超過(guò)80%。

4. 冰上放置5分鐘。12000 rpm(~13,000g)離心1分鐘。 轉(zhuǎn)移上清到新的1.5ml離心管中。

注:轉(zhuǎn)移上清時(shí)確保不要吸取到沉淀,轉(zhuǎn)移的上清量最好不超過(guò)80%

5. 加入與上清等體積的緩沖液R5(使用前請(qǐng)檢查是否已加入異丙醇),顛倒混勻。

6. 取750 μl混合液加到吸附柱中(吸附柱放入收集管中),12000 rpm(~13,000g)離心30秒,倒掉濾出液。

7. 將剩余混合液加到吸附柱中(吸附柱放入收集管中),12000rpm(~13,000g)離心30秒,倒掉濾過(guò)液。

8. 向吸附柱CG中加入500 μl 漂洗緩沖液WB1(使用前請(qǐng)先檢查是否已加入無(wú)水乙醇),12,000 rpm (~13,000×g )  離心30 秒,倒掉廢液。

9. 向吸附柱CG中加入600 μl 漂洗緩沖液PW(使用前請(qǐng)先檢查是否已加入無(wú)水乙醇),12,000 rpm (~13,000g) 離心30 秒,倒掉廢液,吸附柱CG放入收集管中。

10. 向吸附柱CG中加入600 μl漂洗緩沖液PW,12,000 rpm (~13,000g) 離心30秒,倒掉廢液,將吸附柱CG放入收集管中。

11. 12,000 rpm(~13,000g)離心2分鐘,以徹底晾干吸附材料中殘余的漂洗液。

注:此步驟非常重要,其目的是將吸附柱中殘余的漂洗液去除。漂洗液中乙醇的殘留會(huì)影響后續(xù)的酶反應(yīng)(酶切、PCR等)實(shí)驗(yàn)。

12. 將吸附柱CG轉(zhuǎn)入一個(gè)干凈的1.5ml離心管中,向吸附膜的中間部位懸空滴加50–100 μl經(jīng)70水浴預(yù)熱的洗脫緩沖液EB,室溫放置2分鐘,12,000 rpm(~13,000g)離心2分鐘。

= 1 \* GB3 洗脫緩沖液體積最好不少于50 μl,體積過(guò)小影響回收效率。

= 2 \* GB3 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。

13. DNA產(chǎn)物-20保存。

大量操作步驟(針對(duì)含微量核酸的樣品)

1. 稱(chēng)1-5 g土壤置于10ml離心管中,加入1gGlass Beads,再加入3ml 緩沖液R1與200μl 緩沖液R2。渦旋器高速震蕩3-5分鐘。

2. 加入600μl 緩沖液R3,渦旋混勻。70水浴處理10分鐘。期間振蕩幾次。

3.3000g離心3分鐘,轉(zhuǎn)移上清到新的離心管中,加入550μl 緩沖液R4混勻。

4. 冰上放置5分鐘。8000 g離心10分鐘。轉(zhuǎn)移上清到新的離心管中。

5. 以下按標(biāo)準(zhǔn)操作步驟的第五步繼續(xù)操作。

DNA濃度及純度檢測(cè):

基因組DNA片段的大小與樣品保存時(shí)間、操作過(guò)程中的剪切力等因素有關(guān)。提取的DNA片段可用瓊脂糖凝膠電泳和紫外分光光度計(jì)檢測(cè)濃度與純度??膳渲?.8-1.0%瓊脂糖凝膠,使用λ/HindIII判斷基因組的大小,完整的基因組大小應(yīng)在23kb以上。使用分光光度計(jì)檢測(cè)時(shí), OD260/OD280比值應(yīng)為1.7–1.9之間,如果洗脫時(shí)不使用洗脫緩沖液,而使用去離子水洗脫,比值可能偏低,但并不表明DNA純度不高。

常見(jiàn)問(wèn)題分析:

常見(jiàn)問(wèn)題

可能原因

建議

沒(méi)有洗脫出DNA

緩沖液R5沒(méi)有加入異丙醇

樣品過(guò)柱前,必須用異丙醇調(diào)整核酸結(jié)合條件,否則核酸不能掛柱。

漂洗緩沖液PW中沒(méi)有加入乙醇

漂洗緩沖液PW使用前請(qǐng)按照標(biāo)簽加入無(wú)水乙醇。無(wú)水乙醇加入量不正確會(huì)導(dǎo)致核酸提取量大大降低。

低濃度的DNA

緩沖液R2使用過(guò)量

按照步驟1加入適量緩沖液R2

洗脫體積太小

洗脫體積不能低于50μl,如洗脫體積太小,回收率將大大降低。

洗滌不恰當(dāng)

漂洗緩沖液PW使用前請(qǐng)按照標(biāo)簽加入無(wú)水乙醇。無(wú)水乙醇加入量不正確會(huì)導(dǎo)致核酸提取量大大降低。

A260/A280比率

蛋白污染

不要忽略步驟8中用漂洗緩沖液WB1沖洗吸附柱

洗脫液pH值不合適

確保使用的洗脫液pH8.0以上,如低于8.0將導(dǎo)致DNA洗脫量過(guò)低。

下游應(yīng)用不好

提取的DNA含鹽量高

漂洗緩沖液PW使用前請(qǐng)按照標(biāo)簽加入無(wú)水乙醇。

提取的DNA含有乙醇

步驟11空甩柱子2分鐘非常關(guān)鍵,徹底去除漂洗液中的乙醇。

抑制PCR反應(yīng)

增加緩沖液R2用量,徹底去除腐殖酸等PCR抑制因子;步驟4中確保不要吸取到沉淀。

 實(shí)驗(yàn)示例:

Buffer R2去除腐殖酸效果對(duì)比圖
左圖-步驟1提取時(shí)使用了Brffer R2,顏色明顯淺很多(左1,左2),
說(shuō)明Buffer R2對(duì)去除腐殖酸、色素等效果明顯
右圖-步驟3上清加入Buffer R4進(jìn)一步處理,離心去除雜質(zhì),
裂解時(shí)加有Buffer R2的,再經(jīng)Buffer R4處理幾乎不再有顏色(右1,右2),
而不加Buffer R2的顏色還很深(右3,右4)。
