Highlights
- Easy purification of high-quality DNA from whole blood, buffy coat, swabs, or cultured cells.
- Protocol excludes the use of Proteinase K and organic denaturants for biofluid and cell samples.
- Eluted, inhibitor-free DNA is ideal for PCR, endonuclease digestion, bisulfite conversion/methylation detection, sequencing, genotyping, etc.
Description
| Elution Volume | ≥50 µl |
|---|---|
| Equipment | Microcentrifuge, Vortex |
| Purity | High-quality DNA is eluted with DNA Elution Buffer or water. DNA is especially well suited for PCR and other downstream applications. A260/A280>1.8 |
| Sample Source | Whole blood, plasma, or serum from humans, mice, rats, etc. Cells from culture, buccal cells, as well as a variety of biological liquids are effectively processed using this kit. Tissue already digested with Proteinase K or mechanically homogenized. |
| Size Range | Capable of recovering genomic DNA up to and above 40 kb. In most instances, mitochondrial DNA and viral DNA (if present) will also be recovered |
| Workflow | Unique lysis buffer system omits the need for Proteinase K digestion for biological fluids and cell culture samples. |
| Yield | Up to 25 µg total DNA is eluted into ≥50 µl (30 µl minimum) DNA Elution Buffer or water. Human whole blood yields 3-7 µg DNA per 100 µl blood sampled. Mammalian tissues already homogenized will yield 1-3 µg DNA per mg. |
Q1: 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 typically recovers more DNA.
Q2: 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 taking an aliquot for purification.
Q3: Can the Quick-DNA kit be used with bacterial samples?
E.coli cells are easy-to-lyse and can be processed directly. For other microbes, additional pretreatment (e.g. enzymatic digestion or mechanical lysis) can be implemented and then processed with the Quick-DNA Kit. Alternatively, for an all-inclusive kit to process all microbes, use any of Zymo Research’s Environmental Kits (e.g. Quick-DNA Fungal/Bacterial, Quick-DNA Fecal/Soil, ZymoBIOMICS DNA, etc.) for DNA isolation.
Q4: Can I use the Quick-DNA kit to clean-up previously isolated DNA?
No, the kit is designed for direct use with biological samples. For clean-up of isolated DNA, please use the Genomic DNA Clean & Concentrator or the DNA Clean & Concentrator kits.
Q5: 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.
Q6: 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.
Q7: Is it possible to add an RNase A treatment to the protocol?
The Quick-DNA kits recover RNA-free genomic DNA. The selective chemistry allows for binding of double stranded DNA to the column and for RNA to flow through. No RNase A treatment is required when processing samples within kit specifications.
Q8: What are the expected yields for each sample type?
Keep in mind that there is sample to sample variability.
| Sample Type | Input Amount | Expected Yield |
|---|---|---|
| Eukaryotic Cells | 1x106 Cells | 5-6 µg |
| Skeletal, Heart, Lung, Brain Tissue | 1 mg | 1-3 µg |
| Liver and Kidney Tissue | 1 mg | 3-5 µg |
| Human Whole Blood | 100 µl | 5-7 µg |
“It was easy to work with, protocol easy to follow”
-Tinatin T.
“This kit did a good job of prepping clean genomic DNA.”
-Tara N. (United States Agricultural Research Service)
"This product was amazing! I"ve used the same type of kit (quick DNA extract) from Sigma and this was far more superior. I used the same amount of postnatal tissue as I would have for the Sigma kit, however the yield I obtained from Zymo was quite astounding considering the time of tissue digestion. Secondly, the gDNA was much "cleaner" upon measurement with our NanoDrop! "
-Stephen C. (Johns Hopkins University School of Medicine)

单纯从你这个尿常规结果来看：你的上皮细胞数量在正常女性的尿液中算是正常的，镜检白细胞：15——20个/HP，它表示你的泌尿系统可能存在感染。但是，因为没有你的其他资料和其他检查结果，单凭一个结果不能说明太多问题。一般情况下不可能是肾的不好，请不用担心。
我的建议是：
1、去医院复查，但要注意留尿的时候先清洁外阴，留取中段尿。及时化验。
2、如果检查结果仍然有白细胞，可去妇科或泌尿科看医生，一般的感染的话吃点药马上就好了。
3、放松心情，注意个人卫生即可。
目前想建立家系血标本的淋巴细胞的永生化细胞株，请问有哪些成熟的方法及protol，费用贵么？
希望有大神赐教!谢谢！
G418浓度之前师兄已经摸索出来，这次筛选直接用师兄浓度。
1、6孔板转染后多长时间开始进行G418筛选？
2、G418筛选是在6孔板中继续筛选还是转到24/96孔？大皿？
3、G418浓度什么时候减量
4、？筛选过程中荧光观察一小部分克隆不错，如何挑选出来？
5、整个筛选过程大约需要多长时间？
lipo3000筛选
谢谢大家！
红细胞压积，是指红细胞占血液体积的比例，您仅仅是比参考范围略低，同时红细胞数量，和血红蛋白并没有下降，这可能是血液有所稀释所致。
白细胞计数3.9，正常的话 4-10之间，你仅仅是比参考范围略下降一丁点，本身并无意义，参考范围是大致的。而且血液还可能存在稀释可能性
中性粒细胞绝对值和百分比略低一点，同时淋巴细胞百分比略有上升，那这本身就只是略高一点点，而一般比如感冒以后，也往往可以升高，其他的红细胞分布宽度等是派生指标，没大意义的。
总之单单看这一个血常规检验，本身没有什么大的异常发现，当然也可以稍后复查，比如过2周以后复查

指导意见：
毕竟阴道上皮是鳞状上皮,而输尿管,膀胱,尿道的上皮是柱状上皮,形态上是不一样的.所以您要是对您的结果出怀疑态度,首先：重新留尿,做一个复检（留尿时注意防止阴道分泌物污染）；或者让值班医生分析一下是那种类型的上皮（鳞状还是柱状）.所以不要担心这个结果.一般情况下污染的比较多.
