Details
Viagen DirectPCR® DNA Extraction System is a single-tube system forrapid preparation of DNA from mouse tails, ear pieces, yolk sac, andculture cells. The patent-pending components developed by scientists atViagen Biotech Inc. allow the resulting DNA extracts to be compatiblewith genomic PCR for genotyping. Crude extracts of biological samplesare not compatible with many molecular biology-grade reactions such aspolymerase chain reaction (PCR), in part due to inhibitors contained incrude extracts. The DirectPCR reagents not only mediate the rapid lysisof biological samples but also contain inhibitors that effectivelysuppress the inhibitory activities of crude lysates for PCRamplification, while maximally maintaining the integrity of releasedgenomic DNA. The patent-pending simple procedure completely eliminateany solution transfer or tube-opening steps, providing you withsubstancial extra time.
Brief procedure1. Lyse tails in DirectPCR® Lysis Reagent.2. Incubate for 45 min at 85°C.3. PCR genotyping with 1 μl lysates.

根据组成不同,可分为两种,弱酸及其对应的强碱弱酸盐,弱碱及其对应的强酸弱碱盐。
因为HF可以和NaOH反应生成NaF和水,当NaOH反应完之后,NaF就可以与HF组成缓冲溶液,所以说可以直接使用NaOH和HF来配制缓冲溶液。
这也是一般配制缓冲溶液的方法,也就是用强碱和弱酸(或者强酸和弱碱)来配制缓冲溶液。
(2)酸和盐浓度等比例也增减时,溶液的pH值不便。
(3)酸和盐浓度相等时,缓冲液的缓冲效率为最高,比例相差越大,缓冲效率越低,一般地说缓冲液有效缓冲范围为PK±1pH
浙江大学奚振宇、徐又一、朱利平等2009年在journal of membrane science(中文翻译为《膜科学杂志》)发表的一篇论文,其中探讨了缓冲溶液的pH值对聚乙烯-多巴胺复合膜亲水性的影响,发现缓冲溶液的pH值为8.5时制备的复合膜亲水性最强。
通过大量的实验,研究人员发现,pH值为8.5时制备的多巴胺复合膜性能最优。这个是通过大量的实验总结得到的结论。
