- 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

现在有一个实验需要看一种药物与受体的结合情况，想咨询一下放射性配体受体结合实验，因为我们不具备这个实验条件，最好能外包那种
大多数药物在体内都是和特异性受体相互作用，改变细胞的生理生化功能而产生效应。目前已经确定的受体有30多种，根据受体存在的标准，受体可大致分为三类：
1．细胞膜受体：位于靶细胞膜上，如胆碱受体、肾上腺素受体、多巴胺受体、阿片受体等。
2．胞浆受体：位于靶细胞的胞浆内，如肾上腺皮质激素受体、性激素受体。
3．胞核受体：位于靶细胞的细胞核内，如甲状腺素受体。
另外也可根据受体的蛋白结构、信息转导过程、效应性质、受体位置等特点将受体分为四类：
1．含离子通道的受体（离子带受体）：如N-型乙酰胆碱受体含钠离子通道。
2．G蛋白偶联受体：M-乙酰胆碱受体、肾上腺素受体等。
3．具有酪氨酸激酶活性的受体：如胰岛素受体。
4．调节基因表达的受体（核受体）：如甾体激素受体、甲状腺激素受体等。
有些受体具有亚型，各种受体都有特定的分布部位核特定的功能，有些细胞也有多种受体。
