Computer simulations of theoretical PCR results (Electronic PCR) may be performed to assist in primer design. [14] Touchdown polymerase chain reaction or touchdown style polymerase chain reaction is a method of polymerase chain reaction by which primers will avoid amplifying nonspecific sequences.
Primer Premier is a bioinformatics software used for various PCR applications. It supports the design of degenerate primers for amplifying a related set of nucleotide sequences for the detection of common traits amongst organisms, as well as to determine heredity. [1] The software also designs tagged and nested primers for multiplex PCR ...
The design of appropriate short or long primer pairs is only one goal of PCR product prediction. Other information provided by in silico PCR tools may include determining primer location, orientation, length of each amplicon, simulation of electrophoretic mobility, identification of open reading frames, and links to other web resources.

Overhangs should be at least 40 nucleotides long to ensure adequate interaction between fragments. Final amplification primers are commonly designed following general guidelines for PCR, however they are used in 2 to 5 times lower concentration than in standard PCR reactions, as it this has been shown to reduce undesired amplifications. [5]
The free NCBI tool Primer-BLAST integrates primer design and BLAST search into one application, [6] as do commercial software products such as ePrime and Beacon Designer. Computer simulations of theoretical PCR results (Electronic PCR) may be performed to assist in primer design by giving melting and annealing temperatures, etc. [7]
SSB bind to displaced strands of DNA and prevent the primers from being displaced. Finally, the strand displacing polymerase begins DNA synthesis where the primer has bound to the target DNA. By using two opposing primers, much like PCR, if the target sequence is indeed present, an exponential DNA amplification reaction is initiated. No other ...
The kit adapted for carrying out the method includes a pair of primers to amplify the locus and optionally polymerase chain reaction reagents. [17] LCR can be used to diagnose tuberculosis. [18] The sequence containing protein antigen B is targeted by four oligonucleotide primers—two for the sense strand, and two for the antisense strand. The ...
OLIGO Primer Analysis Software is a software for DNA primer design. [ 1 ] [ 2 ] The first paper describing this software was published in 1989. [ 3 ] The program is a real time PCR primer and probe search and analysis tool.
