[求救] gel extraction
各位大哥大姊好阿
我最近在做clone的實驗
已經將insert(900bp)成功接進yT&A當中
現在要大量培養
用兩個限制酶將insert切下再接入另外一個vector中
我取約1ug的plasmid進行RE digest(總反應體積20uL)
37度,2hr;70度水浴,10min,中止反應
全部load進 1% agarose gel跑DNA電泳
用bioman的kit進行gel extraction
用20ul EB進行回溶
問題來了我純化出來的濃度都很低(不超過5ng/uL)
甚至沒有...而且A260/280也不對
kit應該是沒問題
因為我用了別人借同樣的kit還有別牌的kit結果都一樣
喔對~我在離完酒精後會再放入60度的烘箱5~10min(不知道有沒有影響)
有沒有人知道怎麼會這樣@@
