Primer-blast tries to find target-specific primers by placing candidate primers on unique template regions that are not similar to other targets.
Nov 28, 2023 · The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
Primer BLAST performs only a specificity check when a target template and both primers are provided. In the Primer Pair Specificity Checking Parameters section, select the appropriate source Organism and the smallest Database that is likely to contain the target sequence.
Jun 18, 2012 · The Primer-BLAST program was implemented using the NCBI C++ toolkit and the Primer3 C programming interface, which recently added the capability to target primers to one or more specified regions as well as between specified bases (for splice site specification).
Primer-BLAST was developed at NCBI to help users make primers that are specific. to intended PCR target. It uses Primer3 to design PCR primers and then uses. BLAST and global alignment algorithm to screen primers against user-selected database.

Jun 18, 2012 · Primer-BLAST allows users to design new target-specific primers in one step as well as to check the specificity of pre-existing primers. Primer-BLAST also supports placing primers based on exon/intron locations and excluding single nucleotide polymorphism (SNP) sites in primers.
Primer-BLAST was developed at NCBI to help users make primers that are specific to intended PCR target.

Feb 4, 2022 · NCBI's Primer-BLAST combines the primer design features of the popular Primer3 package with a specificity check that uses nucleotide BLAST to search for target and non-target matches in a background database.
