Nickase-dependent isothermal DNA amplification
We developed a nicking endonuclease dependent DNA amplification (NDA), using Nt.BstNBI to catalyze single-stranded nick on double-stranded DNA, and Bst DNA polymerase to make extension while sealing the nick and displacing the downstream strand. The displaced single-stranded DNA thereby serves as template for primers hybridization and extension, resulting in exponential synthesis of target DNA ...
متن کاملHelicase-dependent isothermal DNA amplification.
Polymerase chain reaction is the most widely used method for in vitro DNA amplification. However, it requires thermocycling to separate two DNA strands. In vivo, DNA is replicated by DNA polymerases with various accessory proteins, including a DNA helicase that acts to separate duplex DNA. We have devised a new in vitro isothermal DNA amplification method by mimicking this in vivo mechanism. He...
متن کاملبررسی کارایی روشLAMP (Loop-mediated isothermal DNA amplification)
مقدمه:سالمونلاها از مهمترین باکتری های بیماری و عامل تیفوئید، باکتریمی، آنتروکولیت و سالمونلوز است که از عفونت های مشترک انسان و حیوانات می باشد. بیماریهای ناشی از این عامل یک معضل بزرگ بهداشتی در جهان به خصوص در کشورهای در حال توسعه از جمله کشور ما می باشد. بنابراین تشخیص سریع، دقیق و به موقع آن برای جلوگیری از اپیدمی و عوارض مخرب این باکتری ضروری به نظر می رسد. برای تشخیص سالمونلا روش های مخت...
متن کاملRamification Amplification: A Novel Isothermal DNA Amplification Method
We have developed a novel isothermal DNA amplification method with an amplification mechanism quite different from conventional PCR. This method uses a specially designed circular probe (C-probe) in which the 3 and 5 ends are brought together in juxtaposition by hybridization to a target. The two ends are then covalently linked by a T4 DNA ligase in a target-dependent manner, producing a closed...
متن کاملLoop-mediated isothermal amplification of DNA.
We have developed a novel method, termed loop-mediated isothermal amplification (LAMP), that amplifies DNA with high specificity, efficiency and rapidity under isothermal conditions. This method employs a DNA polymerase and a set of four specially designed primers that recognize a total of six distinct sequences on the target DNA. An inner primer containing sequences of the sense and antisense ...
