Since PCR is often problematic on GC-rich templates, we have evaluated different PCR enhancing additives and generated an Combinatorial Enhancer Solution (CES). We tested this solution on approx. 50 different primer pairs using several different polymerasesThe 5x concentrated Combinatorial Enhancer Solution (CES) contains:2.7 M betaine6.7 mM DTT6.7% DMSO and55 μg/ml BSAAdd this solution to your PCR and see if it work......閱讀全文

PCR進階——GCRich片段的擴增策略
PCR早已是分子生物學實驗的常規技術，但是GC-rich擴增始終是有難度的應用。 以人基因組為例，大約3%的序列可劃為GC-rich序列，尤其是在啟動子，增強子等控制元件，GC-rich序列更為常見。因此，GC-rich片段的PCR擴增困難，也就阻礙了有關這類序列的科研進展。 GC-Rich

高GC含量PCR樣本的擴增困難與防止污染與降解的操作方法
? ? ? ?每天做實驗小心翼翼，時時擔心提取的DNA被污染、被降解。終于，廢了九牛二虎之力，好不容易提取到高質量的DNA，然而PCR仍然P不出來條帶。是試劑加漏了嗎？是酶失活了嗎？換上新試劑，冰上重來一次，然并卵，不僅P不出來，更重要的是也不知道為啥P不出來，貝多芬都彈不出我的悲傷！?? ?

eRNA與Super－Enhancer－RNA在轉錄調控中扮演的角色
增強子是真核生物中關鍵的順式作用基因調控元件，能有效地促進基因表達。它們可以通過作為轉錄因子和輔助因子的結合平臺來維持轉錄的精確控制。超級增強子是由一簇典型增強子串聯組成的具有更強轉錄調控能力的順式元件。而全基因組分析發現增強子和超級增強子可以普遍進行轉錄，產生eRNA和SE-lncRNA。它們都具

高靈敏度化學發光技術應用心得（四）
結論：采用Bio-Rad的冷CCD化學發光成像系統進行化學發光的檢測，比傳統的暗室曝光方法更為簡便，也大大縮短了實驗時間。但在成像時需要注意選擇合適的化學發光試劑，以適合CCD的成像檢測。且大部分的化學發光試劑均對應暗室曝光的方式，因此在進行檢測需要進行調整，如對發光液不能進行稀釋，而必須要使用原液

高GC比模板的PCR擴增
PCR條件的優化是一個麻煩耗時的過程，涉及到溫度、時間、鎂離子、引物、dNTP、Taq酶、模板等多個因素的調整。一般來說利用熱啟動，比如Platinum Taq?DNA聚合酶（Invitrogen）可以達到更高的特異性，降低對鎂離子濃度的依賴，并且有利于提高“問題模板”的產量。然而，傳統的PCR條件
