- 背景资料
- PMA is a high affinity photoreactive DNA binding dye developed by Biotium for viability PCR. PMAxx™ is Biotium's new and improved viability PCR dye. The dyes are weakly fluorescent by themselves but become highly fluorescent upon binding to nucleic acids. Upon photolysis, the dye forms a stable covalent bond with the DNA, thus resulting in permanent DNA modification. The dye is cell membrane-impermeable and thus can be used to selectively modify DNA from dead cells with compromised membrane integrity, while leaving DNA from viable cells intact. PMA and PMAxx™ inhibit PCR amplification of modified DNA templates. Consequently the dye is useful in the selective detection of viable pathogenic cells by quantitative real-time PCR. PMA Enhancer for Gram Negative Bacteria was designed to improve PMA- and PMAxx™-mediated discrimination between live and dead gram-negative bacteria. PMA Enhancer is provided as a 5X solution, and is added to a sample before the addition of dye. When a sequence from a gram-negative bacteria is amplified by PCR, samples pre-treated with Enhancer show a decrease in the signal from dead cells, with no change in the signal from live cells. Thus, PMA or PMAxx™ plus Enhancer is the optimal way to perform viability PCR on gram-negative bacteria. Note: PMA Enhancer is not intended for use when gram-positive bacteria are to be detected. PMA Enhancer may adversely affect the amplification of live cell DNA from gram-positive bacteria. For photoactivation of PMA, PMAxx™ or EMA dye, we recommend the use of Biotium's PMA-Lite™ LED Photolysis Device for tubes, or Glo-Plate™ Blue LED Illuminator for plates, which are designed to conduct photolysis under controlled conditions. Materials from Biotium are sold for research use only.
- 产品描述
- PMA是由Biotium开发的用于活力PCR的高亲和力光反应性DNA结合染料。PMAxx™是Biotium的新的和改进的活力PCR染料。染料本身是弱荧光的,但在与核酸结合时变得高度荧光。在光解时,染料与DNA形成稳定的共价键,从而导致永久的DNA修饰。染料是细胞膜不可渗透的,因此可用于选择性地修饰来自膜完整性受损的死细胞的DNA,同时使来自活细胞的DNA保持完整。PMA和PMAxx™抑制修饰的DNA模板的PCR扩增。因此,该染料可用于通过定量实时PCR选择性检测活病原细胞。nbsp; 用于革兰氏阴性菌的PMA增强剂旨在改善PMA和PMAxx™介导的活革兰氏阴性菌和死革兰氏阴性菌之间的区分。PMA增强剂作为5X溶液提供,并且在添加染料之前添加到样品中。当通过PCR扩增来自革兰氏阴性细菌的序列时,用增强子预处理的样品显示来自死细胞的信号降低,而来自活细胞的信号没有变化。因此,PMA或PMAxx™加增强子是对革兰氏阴性细菌进行活力PCR的最佳方式。注:PMA Enhancer预期不用于检测革兰氏阳性菌。PMA增强子可能不利地影响来自革兰氏阳性细菌的活细胞DNA的扩增。nbsp; 对于PMA、PMAxx或EMA染料的光活化™,我们建议使用Biotium的PMA-Lite™LED光解装置用于管,或使用Glo-Plate™蓝色LED照明器用于板,它们旨在受控条件下进行光解。nbsp; Biotium的材料仅供研究使用。
