● 儲存條件(jiàn)和效期：
該試劑盒常溫貯存，常溫運輸。開封後有效期一年(nián)。
● 産品簡介：
全血基因組DNA
小量提取試劑盒可(kě)從(cóng)200-400 μl體(tǐ)積新鮮、冷(lěng)凍或抗凝全血樣本中快(kuài)速分(fēn)離(lí)純化基因組DNA。該試劑盒可(kě)以在30分(fēn)鍾内完成單個或多個樣品的操作(zuò)。 提取過程無需使用蛋白(bái)酶K消化，不需要酚氯仿抽提，
也無需耗時的異丙醇沉澱等過程 。
使用該試劑盒提取到的DNA
可(kě)以用于PCR，Southern雜交，酶切消化等實驗。
● 準備工(gōng)作(zuò)：
1. 準備無水乙醇；制冰機(jī)；1.5ml離(lí)心管；2ml離(lí)心管；離(lí)心機(jī)
2. 按照(zhào)标簽所示在去(qù)蛋白(bái)液GD和漂洗液PW中加入無水乙醇，混勻後蓋緊瓶蓋後常溫貯存備用。
3. 每次使用前請(qǐng)檢查緩沖液DL1和DL2是否有沉澱生(shēng)成，如(rú)果出現沉澱，37℃溫浴至沉澱溶解後再使用。
● 标準操作(zuò)步驟：
如(rú)非指出，所有離(lí)心步驟均爲使用台式離(lí)心機(jī)在常溫下離(lí)心。
注意：以下方案适用于400
μl體(tǐ)積新鮮或冷(lěng)凍血液樣本。如(rú)果使用低于400 μl的全血樣本，必須按比例減少緩沖液DL1和DL2的用量或者用1×PBS溶液補齊至400 μl，嚴格按照(zhào)緩沖液DL1：全血：緩沖液DL2=3：4：3體(tǐ)積比進行操作(zuò)，否則将導緻後續操作(zuò)無法進行。
1. 加入300μl緩沖液DL1于1.5
ml離(lí)心管中。
2. 加入400
μl抗凝全血，漩渦劇(jù)烈震蕩30秒。 注：如(rú)果低于400 μl血液，用1×PBS補齊到400
μl。
3. 加入300μl緩沖液DL2，劇(jù)烈搖動離(lí)心管3-5次，漩渦劇(jù)烈震蕩30秒-60秒。
注：加入緩沖液DL2後，會出現大(dà)量血紅(hóng)蛋白(bái)沉澱，必須劇(jù)烈震蕩。
4. 12000 rpm 離(lí)心2分(fēn)鍾。
5. 把吸附柱裝在2ml收集管中（已提供），将第4步得(de)到的上清溶液全部轉入柱中（小心别觸及沉澱），12000
rpm離(lí)心1min，倒棄流出液重新套上收集管。
注：吸附柱的承受最大(dà)體(tǐ)積是700 μl，如(rú)上清超過此體(tǐ)積，可(kě)分(fēn)2次離(lí)心，保證所有上清都(dōu)加到柱中。
6.加入500 μl
去(qù)蛋白(bái)液GB（注意是否已經加入乙醇）至柱子中，12000 rpm離(lí)心1min，棄去(qù)流出液。
注：吸附柱膜上會有血色素殘餘，這是正常現象，可(kě)以被去(qù)蛋白(bái)液GD和漂洗液PW洗去(qù)。
7. 将吸附柱重新套回2ml收集管中，加入700μl 漂洗液PW（注意是否已經加入乙醇）至柱子中，12000 rpm離(lí)心1min,倒棄流出液；
8. 再加入500μl
漂洗液PW至柱子中，12000 rpm離(lí)心1min,
棄去(qù)流出液；
9. 将吸附柱重新套回2ml收集管中，12000 rpm離(lí)心空結合柱2 min以幹燥柱子的基質；
注：這一步驟至關重要，不要省略。 否則殘餘乙醇會影(yǐng)響後續酶切或PCR實驗。
10. 将柱子置于1.5ml滅菌離(lí)心管，加入50-80 μl65℃預熱(rè)的洗脫緩沖液EB或滅菌去(qù)離(lí)子水至柱子的膜中央。 常溫靜(jìng)置2 min；
注： ① 洗脫緩沖液體(tǐ)積最好不少于50 μl，體(tǐ)積過小影(yǐng)響回收效率。
② 洗脫液的pH值對于洗脫效率有很大(dà)影(yǐng)響。若用水做洗脫液應保證其pH值在7.0-8.5範圍内，pH值低于7.0會降低洗脫效率。
11. 12000 rpm離(lí)心
2 min洗脫DNA。保留含DNA的流出液。将DNA儲于-20℃。
● DNA濃度及純度檢測：
基因組DNA片段的大(dà)小與樣品保存時間、操作(zuò)過程中的剪切力等因素有關。提取的DNA片段可(kě)用瓊脂糖凝膠電泳和紫外分(fēn)光(guāng)光(guāng)度計(jì)檢測濃度與純度。可(kě)配制0.8-1.0％瓊脂糖凝膠，使用λ/HindIII判斷基因組的大(dà)小，完整的基因組大(dà)小應在23kb以上。使用分(fēn)光(guāng)光(guāng)度計(jì)檢測時， OD260/OD280比值應爲1.7–1.9之間，如(rú)果洗脫時不使用洗脫緩沖液，而使用去(qù)離(lí)子水洗脫，比值可(kě)能偏低，但(dàn)并不表明DNA純度不高。
● 常見(jiàn)問(wèn)題分(fēn)析：
|
常見(jiàn)問(wèn)題
|
可(kě)能原因
|
建議(yì)
|
|
堵柱子
|
樣本體(tǐ)積不對，裂解不完全
|
未按照(zhào)說(shuō)明書(shū)使用指定體(tǐ)積操作(zuò)，請(qǐng)嚴格按照(zhào)緩沖液DL1：全血：緩沖液DL2=3：4：3體(tǐ)積比進行操作(zuò)
|
|
回收不到DNA或得(de)率低
|
堵柱子
|
見(jiàn)上
|
|
化療病人(rén)全血中提取DNA
|
化療病人(rén)血液中白(bái)細胞數量減少，導緻DNA數量降低
|
|
全血樣品保存不當，導緻全血溶血導緻DNA降解
|
4℃冰箱中貯存2周的全血開始出現溶血現象，此時DNA随貯存時間延長會程序分(fēn)解，最終導緻分(fēn)離(lí)不到電泳可(kě)見(jiàn)的DNA；全血應該-20℃或-80℃貯存。
|
|
去(qù)蛋白(bái)液GD和漂洗液PW沒有按說(shuō)明書(shū)加入乙醇稀釋
|
使用前按說(shuō)明書(shū)加入适量的無水乙醇進行稀釋
|
|
DNA純度差
|
高A260/A280比率接近2.0
|
考慮全血樣品的新鮮程度。陳舊全血中的DNA會降解成小片段DNA或核苷酸混合物，導緻A260讀(dú)數變大(dà)
|
|
DNA中有RNA污染
|
使用非常新鮮的全血提取DNA時電泳結果會有RNA污染，RNA不能作(zuò)爲擴增模闆，不會影(yǐng)響PCR擴增。如(rú)要去(qù)除RNA，可(kě)在步驟1加入緩沖液DL1時同步加入5 μl RNaseA溶液（10mg/ml）
|
|
洗滌時柱中有帶顔色的遺留物
|
未按照(zhào)說(shuō)明書(shū)使用指定體(tǐ)積操作(zuò)
|
請(qǐng)嚴格按照(zhào)緩沖液DL1：全血：緩沖液DL2=3：4：3體(tǐ)積比進行操作(zuò)
|
|
去(qù)蛋白(bái)液GB和漂洗液PW沒有按說(shuō)明書(shū)加入乙醇稀釋
|
使用前按說(shuō)明書(shū)加入适量的無水乙醇進行稀釋
