Primer-blast tries to find target-specific primers by placing candidate primers on unique template regions that are not similar to other targets.
Go to the Primer BLAST submission form. Enter the target sequence in FASTA format or an accession number of an NCBI nucleotide sequence in the PCR Template section of the form. If the NCBI mRNA reference sequence accession number is used, the tool will automatically design primers that are specific to that splice variant. If one or both primer ...
Jun 18, 2012 · Primer-BLAST is the only program among the three that will place primers on different exons (i.e., to span an intron) to avoid amplification of genomic DNA and also the only one to allow customization of the number of nucleotide matches on either side of an exon/exon junction.
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 is NCBI’s free online primer design platform which designs PCR primers using the Primer3 system and simultaneously checks the likelihood that the primers will bind to unspecific regions of the organism’s genome via the BLAST algorithm.
We'll use Primer-BLAST to design primers for: A human transcript from the myeloperoxidase (MPO) gene and use the exon/intron selection to make them specific for the transcript. A specific exon of the human MPO gene that contains a clinically signficant SNP. Starting from the nucleotide record.

Oct 14, 2022 · Primer-BLAST is a combination of Primer3, a popular primer designing tool, and NCBI BLAST . Primer-BLAST has two basic modes. It can: Design primers to specifically amplify a template sequence or a set of related templates from a background nucleic acid population (BLAST database).
Primer3Plus picks primers from a DNA sequence using Primer3. This is the latest version straight from the developers with all the new features.
Primer-BLAST can only find non-specific primers for your template since there are other targets that are similar or identical to your template. You may choose to re-search for specific primers by allowing some of the highly similar off-targets if they are irrelevant to your PCR experiment.
