PMA Real-Time PCR Bacterial Viability Kit - E. coli O157:H7 (Z3276)  

※サムネイル画像をクリックすると拡大画像が表示されます。 データシート 商品ページ 概要 PMA-PCR kits are designed for selective detection of viable bacteria from a specific strain using PMA or PMAxx™ dye and real-time PCR. The kits contain PMA dye, Forget-Me-Not™ qPCR Master Mix, and PCR primers for detection of selected strains of bacteria that are of widespread interest to food safety, public health, and/or antibacterial research.  This kit contains primers for amplification of E. coli strain O157:H7 Z3276 gene, with reagents sufficient to treat 80 bacterial cultures with PMA, and perform 200 PCR reactions. The number of samples that can be treated with PMA using the kit may vary depending on sample type.   Kit contents:    PMA dye, 20 mM in water, 100 uL   5X PMA Enhancer for Gram Negative Bacteria, 16 mL   2X Forget-Me-Not™ qPCR Master Mix, 2 x 1 mL (200 reactions)   ROX reference dye, 1 mL   Z3276 primer mix, 5 uM, 400 uL     PMA is a high affinity photoreactive DNA binding dye developed by Biotium. The dye is weakly fluorescent by itself but becomes highly fluorescent upon binding to nucleic acids. It preferentially binds to dsDNA with high affinity. Upon photolysis, the photoreactive azido group on the dye is converted to a highly reactive nitrene radical, which readily reacts with any hydrocarbon moiety at the binding site to form a stable covalent nitrogen-carbon bond, 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 inhibits PCR amplification of modified DNA templates by a combination of removal of modified DNA during purification and inhibition of template amplification by DNA polymerases. Consequently the dye is useful in the selective detection of viable pathogenic cells by quantitative real-time PCR.  Forget-Me-Not™ qPCR Master Mix is a hot-start EvaGreen® dye-based master mix for use in real time PCR applications and DNA melt curve analysis. Forget-Me-Not™ master mix contains a low concentration of blue dye which allows you to see at a glance whether you forgot to add master mix to any of your tubes, so you can catch pipetting mistakes and avoid wasting time, reagents, and your precious DNA samples. It is formulated for qPCR using a fast cycling protocol, but also can be used for qPCR using regular cycling protocols. EvaGreen® dye is a unique DNA-binding dye with features ideal for both qPCR and melt curve analysis. EvaGreen® dye binds to dsDNA via a novel "release-on-demand" mechanism, which permits the use of a relatively high dye concentration in qPCR without PCR inhibition. Forget-Me-Not™ Master Mix contains Cheetah™ Taq, Biotium's fast-activating chemically-modified hot-start Taq polymerase, which is particularly suitable for fast PCR cycling protocols.  E. coli O157:H7 is a pathogenic st	メーカー 品番 包装 BTI 31037 1 KIT 希望販売価格 ¥112,000 ※表示価格について 当社在庫 なし 納期目安 約10日 保存温度 -２０℃     メーカー情報 メーカー名 Biotium, Inc. 略号 BTI 関連情報 同一品名検索
