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

受体是细胞在进化过程中形成的细胞蛋白组分,能识别周围环境中某种微量化学物质,首先与之结合,并通过中介的信息转导与放大系统,触发随后的生理反应或药理效应。自从Langley 提出受体学说100年后,受体已被证实为客观存在的实体,类型繁多,作用机制多已被阐明,现在受体已不再是一个空泛笼统的概念。受体分子在细胞中含量极微,1mg 组织一般只含10fmol左右。能与受体特异性结合的物质称为配体(ligand)。受体仅是一个“感觉器”,对相应配体有极高的识别能力。受体-配体是生命活动中的一种偶合,受体都有其内源性配体,如神经递质、激素、自身活性物(autocoid)等。能激活受体的配体称为激动药(agonist),能阻断其活性的配体称为拮抗药(antagonist)。根据受体与配体结合的高度特异性,受体被分为若干亚型,如肾上腺素受体又分为α1、α2、β1和β2等亚型,其分布及功能都有区别。受体与配体有高度亲和力,多数配体在1pmol~1nmol/L的浓度时即可引起细胞的药理效应。反应之所以如此灵敏主要是靠后续的信息转导系统,如细胞内第二信使(second messenger)的放大、分化及整合功能。酶、载体、离子通道及核酸也可与药物直接作用,但这些物质本身具有效应力,故严格地说不应被认为是受体。某些细胞蛋白组分可与配体结合,但没有触发效应的能力,称为结合体(acceptor)。
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
