Epidermal growth factor receptor (EGFR) gene mutations occur in multiple human cancers; therefore, the detection of EGFR mutations could lead to early cancer diagnosis. This study describes a novel EGFR mutation detection technique. Compared to direct DNA sequencing detection methods, this method is based on allele-specific amplification (ASA), recombinase polymerase amplification (RPA), peptid...
The importance of real-time polymerase chain reaction (PCR) has increased steadily in clinical applications over the last decade. Many applications utilize SYBR Green I dye to follow the accumulation of amplicons in real time. SYBR Green I has, however, a number of limitations that include the inhibition of PCR, preferential binding to GC-rich sequences and effects on melting curve analysis. Al...
BACKGROUND Watermelon silver mottle virus (WSMoV), which belongs to the genus Tospovirus, causes significant loss in Cucurbitaceae plants. OBJECTIVES Development of a highly sensitive and reliable detection method for WSMoV. MATERIALS AND METHODS Recombinant plasmids for targeting the sequence of nucleocapsid protein gene of WSMoV were constructed. SYBR Green I real-time PCR was established...
Since its first use, real-time quantitative PCR (qPCR) has evolved into a flexible, application-made method for the quantification and identification of nucleic acids (1-2). Depending on the application, most researchers choose between fluorescent nucleic acid binding dyes or labels that interact by fluorescence resonance energy transfer (FRET) as nucleic acid detection methods (2-3). Binding d...
We developed a new homogeneous assay-using SYBR Green I and repeats of 20 C nucleotides-for the highly selective and sensitive detection of silver ions and silver nanoparticles.
A simple, rapid, and signal-on fluorescent assay was developed for activity analysis of DNA methyltransferase and for screening of its inhibitors based on a methylation-resistant endonuclease and SYBR Green I.
Combining a DNA intercalator, SYBR Green I, and enzyme-linkage reactions with carbon nanoparticles, a low-background biosensing platform for label-free and sensitive fluorescent assay of DNA methylation is reported.
Fluorescence resonance energy transfer (FRET) is a simple procedure for detecting specific DNA sequences, and is therefore used in many fields. However, the cost is relatively high, because FRET-based methods usually require fluorescent probes. We have designed a cost-effective way of using FRET, and developed a novel approach for the genotyping of single nucleotide polymorphisms (SNPs) and all...
Standardized procedures must be followed when characterizing, officially describing, and validly naming novel bacteria. For species descriptions, DNA-DNA hybridization still is needed for whole-genome comparisons between close relatives, but many established hybridization methods have drawbacks, such as requiring labeled or large amounts of DNA. We evaluated a new technique based on the spectro...
A flow cytometric (FACS) detection method for Plasmodium falciparum cultures (P. falciparum) was developed using SYBR Green I and CD235A and compared against the Giemsa stained microscopic examination. The cultured P. falciparum were spiked into red blood cells (RBCs) to yield parasitemia, ranging from 0.01% to 22.0%. FACS analysis demonstrated a clear separation between P. falciparum infected ...
