Description
| Elution Volume | ≥ 35 µl |
|---|---|
| Equipment | Water bath or heat block (55°C), microcentrifuge, and vortex. |
| Purity | High quality DNA is ready for all sensitive downstream applications such as PCR, endonuclease digestion, Southern blotting, genotyping, Next-Gen sequencing, bisulfite conversion, etc. (A260/A230≥ 2.0). |
| Size Range | Capable of recovering genomic and mitochondrial DNA sized fragments > 50 kb. If present, parasitic, microbial, and viral DNA will also be recovered. |
| Workflow | Utilize a Proteinase K Digestion and Zymo-Spin Column for effective recovery of DNA. |
| Yield | The DNA binding capacity of the column is 25 µg. Typically, mammalian tissues yield: 1-3 µg DNA per mg skeletal, heart, lung, and brain tissues and 3-5 µg DNA per mg liver and kidney. Human whole blood will yield 3-7 µg DNA per 100 µl blood sampled. |
Q1: What is the difference between the digestion buffers? Can one buffer be used for all sample types?
The BioFluid & Cell Buffer (Red) is designed to allow for rapid Proteinase K digestion with easy-to-lyse samples (e.g. mammalian cells and biological fluids).The Solid Tissue buffer (Blue) can be used for any sample type and requires a longer PK digestion time compared to using the BioFluid & Cell Buffer (Red).
Q2: What is the difference between Quick-DNA and Quick-DNA Plus kits?
The Quick-DNA is optimized for cells, soft tissues, and homogenized/digested samples using a single lysis/binding buffer. The Quick-DNA Plus kits contain an optimized Proteinase K for processing a wider variety of sample inputs, such as cells, blood, tissues, etc. The upgraded Quick-DNA Plus recovers more DNA with higher purity compared to the Quick-DNA Kits.
Q3: Can Proteinase K digestion be performed overnight in DNA/RNA Shield?
Yes, samples can be digested overnight. Make sure to follow the appendix (page 8 appendix B) for processing liquids samples in DNA/RNA Shield and incubate at room temperature.
Q4: I’m seeing some yield inconsistencies with my blood samples, what’s happening?
White blood cells, which are the major source of genomic DNA in blood, easily and quickly settles. Mix the blood sample well prior to aliquoting for purification.
Q5: Can the Quick-DNA Plus kit be used with bacterial samples?
E.coli cells are easy-to-lyse and can be processed directly with the Biological Fluids & Cells protocol. For an all-inclusive kit with any type of microbes (including tough-to-lyse), use any of Zymo Research’s Environmental Kits (e.g. Quick-DNA Fungal/Bacterial, Quick-DNA Fecal/Soil, ZymoBIOMICS DNA, etc.).
Q6: Can I use Quick-DNA Plus to clean-up previously isolated DNA?
No, the kit is designed for direct use with biological samples. For clean-up of previously isolated DNA, please use the Genomic DNA Clean & Concentrator or the DNA Clean & Concentrator kits.
Q7: What is the purpose of adding beta-mercaptoethanol? Can this step be substituted or omitted?
Beta-mercaptoethanol is a reducing agent that helps break down proteins and improves DNA recovery and purity. Addition of beta-mercaptoethanol is recommended to enhance sample lysis, but can be substituted with dithiothreitol (DTT, final concentration of 10 mM) or omitted.
Q8: Can Quick-DNA process crude lysates?
Yes, add 4 volumes of Genomic Lysis Buffer to 1 volume of crude lysate, homogenized, or digested sample (see Cell Suspensions and Proteinase K Digested Samples) and proceed with the remainder of the protocol.
This kit is easy to use and provides a high quality yield.

碳酸氢钠溶液是一种co2缓冲液,当瓶内二氧化碳量减少时,碳酸氢钠溶液释放co2,反之吸收co2.因此它能保持瓶内二氧化碳量大致不变.
求采纳为满意回答。
1、 缓冲溶液对反应物的测定没有干扰
2、缓冲组分的浓度为1:1
3、有足够的缓冲容量
4、缓冲溶液的PH应在所需范围内
5、组成缓冲溶液的弱碱PKB和弱酸PKA应接近或等于所需的POH值或PH值（PH+POH=14）
配制
只要知道缓冲对的PH值，和要配制的缓冲液的pH值（及要求的缓冲液总浓度），就能按公式计算[盐]和[酸]的量。这个算法涉及对数换算，较麻烦，前人为减少后人的计算麻烦，已为我们总结出pH值与缓冲液对离子用量的关系并列出了表格。只要我们知道要配制的缓冲液的pH，经查表便可计算出所用缓冲剂的比例和用量。例如配制500nmpH5.8浓度为0.1M磷酸缓冲液。
经查表知pH5.8浓度为0.2M Na2HPO48.0毫升，而0.2M Na2HPO492.0毫升。依此可推论出配制100ml0.1M的磷酸缓冲液需要0.1M Na2HPO48.0毫升，而0.1M Na2HPO4需要92.0毫升。
计算好后，按计算结果准确称好固态化学成分，放于烧杯中，加少量蒸馏水溶解，转移入50ml容量瓶，加蒸馏水至刻度，摇匀，就能得到所需的缓冲液。
各种缓冲溶液的配制，均按表格按比例混合，某些试剂，必须标定配成准确浓度才能进行，如醋酸、氢氧化钠等。另外，所有缓冲溶剂的配制计量都能从以上的算式准确获得。
