objective: polymerase chain reaction (pcr) is one of the most important progress in the field of molecular biology and diagnosis. despite simplicity in concept, the reaction needs complex interaction between target sequence, primers, dntps and dna polymerase for a successful amplification and diagnosis. for the detection of rna viruses highly sensetive and specific technique is required. hence ...

Real-time PCR at the single bacterial cell level is an indispensable tool to quantitatively reveal the heterogeneity of isogenetic cells. Conventional PCR platforms that utilize microtiter plates or PCR tubes have been widely used, but their large reaction volumes are not suited for sensitive single-cell analysis. Microfluidic devices provide high density, low volume PCR chambers, but they are ...

In article number 2100430 by Sung Gap Im, Kyoung G. Lee, and co-workers, an “all-in-one tube” is devised coating poly-(2-dimethylaminomethyl styrene) (pDMAMS) on a polymerase chain reaction (PCR) tube via initiated chemical vapor deposition (iCVD) to extract, amplify, detect pathogens within single tube. The all-in-one can capture the DNA of charge interaction directly perform real-time PCR, re...

With the introduction of real-time, fluorescence-based 5′ nuclease PCR (3,4) and instruments such as the ABI PRISM 7700 (TaqMan) sequence detector (Applied Biosystems, Foster City, CA, USA), quantitative RT-PCR is now a widely accepted method for measuring gene expression levels. Quantitative RTPCR is a sensitive technique and is particularly useful for the analysis of samples containing limi...

A method for fluorescent postlabeling of PCR products has been developed. The method uses Klenow fragment of DNA polymerase I that exchanges the 3'-terminal residue of PCR-amplified DNA fragment for fluorescent nucleotides. All reactions, including PCR, are performed in one tube simply by successive addition of reagents. The products can be applied directly to fluorescence-based automated DNA s...
