We describe an efficient method to separate single-stranded DNA, double-stranded DNA and RNA molecules from environmental viral communities. Nucleic acids are fractionated using hydroxyapatite chromatography with increasing concentrations of phosphate-containing buffers. This method permits the isolation of all viral nucleic acid types from environmental samples.

Chip-in-a-Tube-Based Digital PCR for Quantification of Single Nucleotide Variants

2025
This video demonstrates the utility of digital PCR in a chip-in-a-tube format for the detection of single nucleotide variations in DNA samples. A single PCR reaction is partitioned into chambers that act as independent PCR reactions, and the detection of fluorescence signals from the amplified targets in the chambers is used to compute the frequency of the variant allele in the sample.
FAQs
The strand ratio is established by the relative concentrations of the two primers. The limiting primer sets the point at which one amplification direction slows because that primer becomes depleted. Meanwhile, the excess primer remains available for extension in later thermal cycles. Adjusting this imbalance therefore controls how strongly the reaction favors the desired single-stranded product.
Once the limiting primer has been depleted, it can no longer support equivalent amplification of its associated strand. The excess primer can still extend the complementary target during later thermal cycles, so newly generated product becomes increasingly enriched for one strand. This staged change explains why the final material is predominantly, rather than necessarily exclusively, single stranded.
Compared with amplification that produces both DNA strands in a more balanced way, Single Stranded Pcr supplies a product with a defined strand bias. That distinction matters when a downstream assay needs one sequence orientation, such as hybridization or sequencing. The method is therefore selected not only to copy a target, but also to shape the form of the amplified material.
Strand-specific output can improve downstream hybridization because the available product has a preferred sequence orientation for pairing with a probe or other complementary target. It can also support sequencing workflows in which a defined template strand is useful for analysis. The benefit is analytical: researchers gain a product prepared for a particular downstream interaction rather than an undifferentiated amplification product.
To set up Single Stranded Pcr, researchers use two primers at unequal concentrations and identify which primer will be limiting. Thermal cycling then allows both primers to participate initially, while later cycles favor extension by the primer present in excess. The key procedural decision is the concentration relationship, because primer depletion drives the change in strand representation over the reaction.
For pathogen-focused work, the amplified strand can support detection of a microbial target while also providing material for sequence analysis. The same reaction concept can help identify mutations when the relevant target sequence is examined after amplification. Its value extends beyond indicating whether target nucleic acid is present, because the strand-enriched product can enter additional analytical workflows.
In immunology, the approach can prepare strand-specific DNA probes for studying immune-related genes; in infection research, it can serve the same purpose for microbial targets. These applications connect the amplification design to questions about host or pathogen sequences. The important outcome is a strand-enriched product that can support hybridization, sequencing, or mutation-focused analysis in either research setting.
