Development of a 16S rRNA gene sequence as a biomarker specific to the gastrointestinal tract and feces of swine based on suppressive subtractive hybridization
… marker were compared in a phylogenetic tree. The SYBR green qPCR assay did show amplification of sequences in cattle, human, and two non-target soil samples; however, apparent positive detection of the swine marker was rejected based on dissociation profiles. Therefore, the SYBR green qPCR assay …

Hybrid Cyclic/Linear Peptides in a Multi-Component Lipid Structure as a siRNA Delivery System
… to improve siRNA internalization into the cell. SYBR Green II dye exclusion assay showed a high binding affinity of the peptides with siRNA. The delivery of siRNA into the cells was further enhanced by incorporating hybrid peptides into a multi-component structure called Peptide/Lipid-Associated …

Artemisinin-Based Combination Therapy (ACTs) Drug Resistance Trends in <em>Plasmodium falciparum</em> Isolates in Southeast Asia
… falciparum were cultured and then assayed using SYBR green as an indicator to obtain drug IC50s. The data suggested that many isolates are not demonstrating resistance to artemisinin. However, a select few are showing some resistant characteristics in the form of elevated IC 50s, especially to …

DENVax live attenuated chimeric dengue vaccine
… using two fluorescence-based methodologies, SYBR Green and TaqMan. The SYBR Green method was used to test the virus samples and reproducible results were obtained. The TaqMan assay allows for multiplexing, which allows simultaneous detection of two PCR products; Vero cell DNA present in virus …

High resolution meltcurve PCR assay for detection of salmonella and escherichia coli O157:H7 in foods
… to yield a higher resolution plot compared with SYBR Green I PCR. HRM dyes completely saturate all amplicons without showing preferential bindings, making the results more clear and distinct. In this research, a multiplex real-time PCR targeting the invA, fimA and stn genes were developed to …

An evaluation of genetic markers for forensic identification of human body fluids
… limit of detection (LOD) were investigated using SYBR Green and Taqman probes. The results of the SYBR Green efficiency test experiment displayed five markers, UCE, TEF, ACTB, B2M, and RPS29 with 90-110% efficiency with a slope -3.33 ± 10%. Subsequently, Taqman probes were designed for the five …

Aumento diferencial da expressão de IL13 e CCL17 em mucosite: uma análise comparativa com saúde e peri-implantite
… A análise de RT-PCR foi realizada utilizando o SYBR green para cfRNA dos genes IL13, CCL17 e IL8. A análise dos dados clínicos como comorbidades sistêmicas, idade e sexo não demostraram diferença estatística para os três grupos, enquanto que o fenótipo peri-implantar classificado em fino ou …

The Development of New Tools to Investigate Alphavirus Replication Kinetics
… compared to a double-stranded DNA-specific dye, SYBR Green. Using this information, we determined the replication kinetics of two different genotypes of o'nyong nyong virus (ONNV) and chikungunya virus (CHIKV) in infected mosquito cells. We found that (-) strand viral RNAs persisted in …

Evaluation of the Role of Epstein-Barr virus and Cellular Gene Expression in Paediatric and Adult Transplant Recipients
… We used real-time two-step RT-PCR assays with SYBR green detection to analyse EBV gene expression (76 lytic, 12 latent [n = 88 genes]), following 12-O-tetradecanoyl-13-phorbol acetate/sodium butyrate (TPA/NaB) induction of Raji cells. We identified 22 highly induced EBV genes (>90-fold) at 24 …
