注：以50μl PCR反應(yīng)體系為例，每次使用25μl 2×MasterMix，500μl可做20次 50μl PCR反應(yīng)。
● 儲(chǔ)存條件: -20℃可長(zhǎng)期保存；4℃穩(wěn)定貯存3個(gè)月。經(jīng)常使用時(shí)，一旦融化后請(qǐng)4℃貯存，盡量避免反復(fù)凍融。
● 產(chǎn)品簡(jiǎn)介：
本產(chǎn)品包含Taq DNA聚合酶、dNTPs、MgCl2、反應(yīng)緩沖液、PCR反應(yīng)的增強(qiáng)劑和優(yōu)化劑以及穩(wěn)定劑，濃度為2×。使用時(shí)，只需補(bǔ)加實(shí)驗(yàn)所需的引物和模板后即可進(jìn)行PCR反應(yīng)，可最大限度的減少人為誤差，具有快速簡(jiǎn)便、穩(wěn)定性好等優(yōu)點(diǎn)。適用于常規(guī)PCR反應(yīng)、復(fù)雜模板（如GC含量高，有二級(jí)結(jié)構(gòu)）的擴(kuò)增以及大規(guī)模基因檢測(cè)。使用該產(chǎn)品得到的PCR擴(kuò)增產(chǎn)物末端含有一個(gè)A堿基，可以直接用于TA克隆。
● 質(zhì)量控制：
經(jīng)檢測(cè)無(wú)外源核酸酶活性；PCR方法檢測(cè)無(wú)宿主殘余基因組DNA；能有效地?cái)U(kuò)增人基因組中的單拷貝基因。
● 使用說(shuō)明：
1. 冰浴中徹底融化2×MasterMix，混勻后Minispin將溶液收集到管底。
2. 按照下表在0.2ml PCR管中制備反應(yīng)體系：
