Q1: My lysate seems viscous. What is causing this to happen? How can I fix this?
A viscous sample can indicate incomplete sample lysis. Try using less of your sample and optimize bead beating conditions (duration, speed, time) to ensure samples are thoroughly lysed. After bead beating, pellet the cell debris before moving on. Adding more Genomic Lysis buffer to the lysate can help dilute and deproteinate the sample, making the sample less viscous and more suitable for DNA recovery.
Q2: Are there any tips in optimzing bead beating conditions?
We have validated our kits with both high-speed homgenizers and low-speed disruptors. We highly recommend users to optimize their bead beating conditions for their own instruments. We recommend using a 2 ml-tube adapter to ensure that the bead beating is efficent (do not use adapters made of foam). For high-speed homogenizers, we recommend a total of 5 mins bead beating (1 min interval at 6.5 m/s with 5 mins rest, repeat 5 times). For low-speed cell disruptors, we recommend 30 mins at max speed.
Q3: What is the purpose of Zymo-Spin II-µHRC step?
Environmental samples often contain inhibitors such as polyphenolics, humic/fulvic acids, tannins, melanins, etc. that affect downstream applications such as PCR. Once the DNA is eluted off the binding column, the DNA is then passed through the Zymo-Spin II-µHRC to remove the PCR inhibitors, and the DNA is then ready for downstream applications. The Zymo-Spin II-µHRC does not bind DNA, it simply removes the PCR inhibitors.
Q4: Is it necessary to add beta-mercaptoethanol? Can this step be substituted or omitted?
Addition of beta-mercaptoethanol is recommended to enhance sample lysis, but can be substituted with dithiothreitol (DTT, final concentration of 10 mM). However, if bead beating is optimized and lysis is efficient, the addition of BME is not necessary and can be omitted.
Q5: When can an RNase A treatment be implemented in the protocol?
No additional RNase A treatment is required when processing samples within kit capacity. The selective chemistry allows for binding of double stranded DNA to the column and for RNA to flow through.

请各位大侠给予帮助!!
谢谢!!
健那绿染液是一种活体染液,实验对象必须是活细胞,健那绿可以使活细胞中的线粒体呈现蓝绿色,而细胞质接近无色。
1、快讯上是Invotrogen公司的SYRBGOLD,不过500ul/1390元,实在有点贵,为了查用量;
2、结果又查出赛百盛的GoldViewTMDNA染料1ml/100元;
3、还有一种在日光下即可看出DNA条带的上海华舜生物工程有限公司的LightBluedye;
为了一个EB,居然不小心查出三种染料,而对这三种染料的评价也褒贬不一,我个人希望找个毒害小些,而且灵敏度还不能低于EB,价格方面也能让老板接受的来。
而对这三个染料,我有三个问题:
1、SYRBGOLD的用量问题,500ul能用到200次吗(我一般一次用30ml的胶,配在胶中)?
2、GoldViewTMDNA染料的成分是否如有些人所说的就是丫啶橙(能举出确切证据吗)?
3、LightBluedye灵敏度如何?能比得过EB吗?
前一阵子实验室开始使用一种新的核酸染料-goldview,取代原先用的溴化乙锭-EB.goldview现在是由赛百盛出售.以下摘自官方网站:
GoldViewTM核酸染料——使用说明
概述
GoldViewTM是一种可代替溴化乙锭(EB)的新型核酸染料,采用琼脂糖电泳检测DNA时,GoldViewTM与核酸结合后能产生很强的荧光信号,其灵敏度与EB相当,使用方法与之完全相同。在紫外透射光下双链DNA呈现绿色荧光,而单链DNA呈红色荧光。GoldView不仅能染DNA,也可用于染RNA。
通过Ames试验、小鼠骨髓嗜多染红细胞微核试验、小鼠睾丸精母细胞染色体畸变试验,致突变性结果均为阴性;而溴化乙锭(EB)是一种强致癌剂。因此用GoldviewTM代替EB不失为一种明智的选择。
使用方法
1.将100ml琼脂糖凝胶溶液(浓度一般为0.8%~2%)在微波炉中融化。
2.加入5µlGoldView,轻轻摇匀,避免产生气泡。
3.冷却至不烫手时倒胶,待琼脂糖凝胶完全凝固后上样电泳。
4.电泳完毕在紫外灯下观察。若使用数码相机照像记录,则关闭相机的闪光灯,放在自动档即可;若使用凝胶成像系统照相,通过调节光圈、曝光时间,选择合适的滤光片,可得到成像清晰、背景较低的照片。
注意事项
1.胶厚度不宜超过0.5cm,胶太厚会影响检测的灵敏度。
2.加入GoldView的琼脂糖凝胶反复融化可能会对核酸检测的灵敏度产生一定影响,但不明显。
3.通过凝胶电泳回收DNA片段时,建议使用GoldView染色,在自然光下切割DNA条带,避免紫外线与EB对目的DNA产生的损伤,可明显提高克隆、转化、转录等分子生物学下游操作的效率。
4.虽然未发现GoldView有致癌作用,但对皮肤、眼睛会有一定的刺激,操作时应戴上手套。
电泳结果显示GV灵敏度与EB相当
问题1.Goldview到底是不是丫啶橙?
2.赛百盛不公布其成分的原因是害怕其为丫啶橙还是出于技术保密?
而且样品中的无水硫酸钠未变色,而做标准曲线的五个和空白对照的变为蓝色了,请高手指教,多谢!
还有,是否变蓝对测定结果有影响吗?
谢了哈
欢迎你!请下次规范发贴:)

菁染料是性能优良的荧光标记染料,摩尔吸光系数在荧光染料中是最高的。N-羟基琥珀酰亚胺酯是最常用的脂肪氨基标记试剂,广泛用于蛋白质、氨基酸多肽、抗体、核酸及其他生物分子的标记和检测。通过改变次甲基链的长度,可改变其荧光发射波长,每增加一个双键,按照Huoffman规则正好红移约100nm。
菁染料Cy3和Cy5已成为基因芯片的首选荧光标记物;另外,Cy5,Cy5.5和Cy7,Cy7.5的吸收在近红外区背景非常低,是荧光强度最高、最稳定的长波长染料,特别适合于活体小动物体内成像。但由于菁染料,尤其是不对称菁染料的合成副反应多,副产物极性相近,产物的分离提纯相当困难。菁染料特别是水溶性菁染料分子极性大,分离提纯越加困难。Lumiprobe供应脂溶性和水溶性菁染料。
