dsGreen for Real-Time PCR, 100×

dsGreen for Real-Time PCR, 100× is a double-stranded DNA-binding fluorescent reagent designed for quantitative real-time PCR workflows. In standard qPCR and qRT-PCR assay formats, dsGreen reports DNA amplification by generating a fluorescence signal proportional to the accumulation of double-stranded PCR products, enabling routine monitoring on common real-time PCR instruments. Because dsGreen is intended for dsDNA-dependent signal generation, it is commonly used in assay development and amplification optimization where a straightforward nucleic-acid readout is required.

1. qPCR Amplification Monitoring

dsGreen for Real-Time PCR, 100× is used in real-time PCR to track the formation of double-stranded DNA during thermal cycling. Researchers and assay developers incorporate the reagent into qPCR master mixes to obtain amplification curves and cycle threshold (Ct) values from dsDNA accumulation, supporting routine quantification workflows for DNA targets. This application is particularly common in molecular biology laboratories and industrial R&D settings where robust, plate-based amplification monitoring is needed for screening primer/probe sets, optimizing cycling parameters, and comparing assay conditions.

2. qRT-PCR cDNA Quantification

dsGreen for Real-Time PCR, 100× also fits qRT-PCR workflows where cDNA produced from RNA templates is quantified by monitoring dsDNA amplicons. Molecular diagnostics research groups and gene-expression assay developers use the reagent to generate real-time amplification traces for cDNA targets, facilitating relative quantification experiments and normalization strategies across multiple samples. In these workflows, dsGreen's dsDNA-dependent fluorescence provides a consistent readout across plates, supporting throughput in expression studies and nucleic acid analysis pipelines.

3. End-Point Verification Support

dsGreen for Real-Time PCR, 100× is frequently used alongside downstream analytical steps to confirm that amplification produced the expected dsDNA product population. After qPCR cycling, laboratories may use the same amplification products for orthogonal checks such as melt curve analysis (where instrument workflows support it) or gel-based verification, using the real-time signal as the primary amplification metric. This application supports troubleshooting in primer design iterations, helping teams interpret whether changes in fluorescence behavior correspond to altered amplification efficiency or off-target amplification patterns.
