NetPrimer is a gratis web-based tool used for analysing primers used in PCR to amplify a DNA sequence. [2] The software predicts the melting temperature of the primers using the nearest neighbor thermodynamic algorithm. The accurate prediction of the melting temperature (Tm) is one of the most important factors that governs the success of a PCR ...

The result is a stem-loop primer that excludes annealing involving shorter overlaps, but permits annealing of the primer to its fully complementary sequence in the target. Chimeric primers: some DNA bases in the primer are replaced with RNA bases, creating a chimeric sequence. The melting temperature of a chimeric sequence with another chimeric ...
Droplet Digital PCR (ddPCR) is a method of dPCR in which a 20 microliter sample reaction including assay primers and either Taqman probes or an intercalating dye, is divided into ~20,000 nanoliter-sized oil droplets through a water-oil emulsion technique, thermocycled to endpoint in a 96-well PCR plate, and fluorescence amplitude read for all ...
The oligo-dT primer anneals to the poly-adenylated tail of the mRNA to serve as a binding site for the reverse transcriptase to begin reverse transcription. An optimized mixture of oligo-dT and random hexamer primers increases the chance of obtaining full-length cDNA while reducing 5' or 3' bias. [ 14 ]
A random hexamer or random hexonucleotides are for various PCR applications such as rolling circle amplification to prime the DNA.. They are oligonucleotide sequences of 6 bases which are synthesised entirely randomly to give a numerous range of sequences that have the potential to anneal at many random points on a DNA sequence and act as a primer to commence first strand cDNA synthesis.
Oligonucleotide synthesis is the chemical synthesis of relatively short fragments of nucleic acids with defined chemical structure ().The technique is extremely useful in current laboratory practice because it provides a rapid and inexpensive access to custom-made oligonucleotides of the desired sequence.
