Product Description
The ISOLATE II RNA Mini Kit provides a simple, efficient column-based method for the isolation of total RNA from a wide variety of starting materials, without the need for hazardous reagents such as phenol.
By combining the stringency of guanidinium-thiocyanate lysis with the speed and ease-of-use of silica-membrane purification, the ISOLATE II RNA Mini Kit provides a fast method for the purification of high-quality total RNA from animal and plant cells and tissues as well as cultured cells, bacterial cells, yeast, biological fluids and cell-free samples.
Biological samples which are sometimes difficult to process i.e. mouse tissue (liver, brain), various tumor cell lines, Streptococcus and Actinobacillus pleuropneumoniae, will yield high-quality RNA with the ISOLATE II RNA Mini Kit.
The online product manual has protocols for purifying total RNA from cultured cells, tissues, yeast, bacteria, biological liquids, paraffin embedded tissue and RNAlater® treated samples. There is also a protocol for a convenient on-column DNase treatment, using RNase-free DNase I that is supplied with the kit, for applications that are sensitive to very small amounts of DNA.
The ISOLATE II RNA Mini Kit has been designed to deliver optimal performance in RT-qPCR in conjunction with either the SensiFAST cDNA Synthesis Kit and SensiFAST Real-Time PCR Kits, or the SensiFAST One-Step Real-Time RT-PCR Kits. Additionally, the ISOLATE II RNA Mini Kit can be used to purify samples for PCR and RT-PCR amplification using the Tetro cDNA Synthesis Kit and any enzyme from the Meridian PCR portfolio, including MyTaq DNA Polymerase.
Applications
- RT-qPCR
- End-point RT-PCR
- Northern, dot and slot blotting
- Array analysis
- Poly A+ RNA selection
- RNA-Seq

逆转录(reverse transcription)是以RNA为模板合成DNA的过程,即RNA指导下的DNA合成。此过程中,核酸合成与转录(DNA到RNA)过程与遗传信息的流动方向(RNA到DNA)相反,故称为逆转录。逆转录过程是RNA病毒的复制形式之一,需逆转录酶的催化。 逆转录过程的揭示是分子生物学研究中的重大发现,是对中心法则的重要修正和补充。人们通过体外模拟该过程,以样本中提取的mRNA为模板,在逆转录酶的作用下,合成出互补的cDNA,构建cDNA文库,并从中筛选特异的目的基因。该方法已成为基因工程技术中最常用的获得目的基因的策略之一。
1.模板提取(一般为RNA):Trizol、氯仿、异丙醇、无水乙醇、DEPC处理水
2.模板浓度测定:分光光度计或NanoDrop
3.逆转录:逆转录试剂盒(或者一步法试剂盒),这一步可以用普通PCR做,也可以用水域做。
4.荧光定量PCR试剂:通常有用SYBR Green Mix做的,但是这里建议你用EvaGreen做,灵敏度和平行性都要好于SYBR Green,并且如果你那是ABI或者Stratagene的PCR如果用SYBR Green还需要加一步Rox很麻烦。
5.其他:除了以上的那些还需要离心管、PCR管或板(Axygen反应比较好)、移液枪等,暂时就想到这么多。
