- High-performance – recovery of consistently high quality RNA from a wide variety of animal, bacterial and plant cells and tissues and cell-free samples
- Efficient – optimized lysis conditions and column matrix for recovery of up to 70 mg of high purity RNA from each sample
- Convenient – includes all necessary components, including filters (shredders) and DNase I
- Safe - no hazardous phenol/chloroform extraction, CsCl centrifugation, LiCl or alcohol precipitation
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

加尾法是采用加A酶先对mirna进行加尾,然后再用带oligodt的引物反转录,他的反转录引物是通用的,一次反转录可以获得所有miRNA的cdna,效率高。茎环法是采用特异性反转录引物序列+颈环结构作为反转录引物进行反转录的,一次反转录只能获得一种mirna的cdna,可能有几种一起反转录的,这个我不太清楚一起反转录的效果。然后茎环法的经典即ABI的探针法定量试剂盒。我用过茎环法反转录+染料法定量的,下游引物为通用引物,结果不太好,就现在用的这家的他采用的是双向引物都是特异性的,效果还可以。不知道我说的清楚不,希望能对你有帮助。
如果是用转录出的cDNA做那跟平时就一样了。不需要特别的试剂盒、
