The Ultimate Guide to PCR Primer Design using Primer Premier 6
Primer Premier 6: A Comprehensive PCR Primer Design Software
Have you ever wondered how scientists can make millions of copies of a specific DNA region in a test tube? This amazing technique is called polymerase chain reaction (PCR), and it is widely used in biomedical research, genetic testing, forensic science, and many other fields. PCR allows scientists to amplify a very small amount of DNA and study it in detail.

However, PCR is not as simple as it sounds. It requires careful planning and optimization of many factors, such as the temperature, the duration, and the reagents used in the reaction. One of the most critical reagents for PCR is the primer, a short piece of DNA that binds to the template DNA and provides a starting point for DNA synthesis. Choosing the right primers for your PCR experiment can make a huge difference in the quality and quantity of your results.
That's where Primer Premier 6 comes in. Primer Premier 6 is a software developed by PREMIER Biosoft that helps you design and analyze PCR primers. Primer Premier 6 uses a sophisticated algorithm that finds optimal primers for your DNA sequence, taking into account various parameters such as melting temperature, GC content, secondary structure, specificity, and more. Primer Premier 6 also allows you to design primers for single nucleotide polymorphism (SNP) genotyping assays, which are used to detect genetic variations in DNA. Whether you are doing standard PCR, multiplex PCR, or SNP genotyping, Primer Premier 6 can help you find the best primers for your purpose.
Features of Primer Premier 6
Primer Premier 6 has many features that make it a powerful and versatile tool for PCR primer design. Here are some of the main features that you can use with Primer Premier 6:
Primer design for standard PCR assays
If you want to design primers for a standard PCR assay, you can follow these steps with Primer Premier 6:
Load your template sequence from NCBI or upload a FASTA file. You can enter an accession number, a gene name, or a FASTA sequence in the PCR Template box. You can also specify a range of nucleotides to limit your search.
Specify your primer parameters and PCR product size. You can adjust various parameters such as primer length, melting temperature, GC content, maximum difference between forward and reverse primers, etc. You can also set the minimum and maximum size of your desired PCR product.
View and rank the primer pairs. Primer Premier 6 will generate a list of primer pairs that meet your criteria and rank them according to their quality score. The quality score is based on several factors such as specificity, stability , and efficiency. You can also view the primer sequences, their locations on the template, and their properties such as melting temperature, GC content, and self-complementarity.
Analyze the primer properties and specificity. You can select a primer pair and click on the Analyze button to see more details about the primer properties, such as hairpin formation, dimer formation, and cross-dimer formation. You can also check the specificity of your primers by performing a BLAST search against the NCBI database or a local database. This will help you avoid non-specific amplification and false positives.
Primer design for SNP genotyping assays
If you want to design primers for SNP genotyping assays, you can follow these steps with Primer Premier 6:
Load your SNPs from dbSNP or GenBank files. You can enter an rs number, a gene name, or a GenBank file in the SNP Template box. You can also specify a range of nucleotides to limit your search.
Design primers for probe-based detection of SNPs. Primer Premier 6 supports two types of probe-based detection methods: TaqMan and Molecular Beacon. You can choose the type of probe you want to use and adjust the probe parameters such as length, melting temperature, GC content, etc. Primer Premier 6 will design primers and probes that are specific for each allele of the SNP.
View and rank the SNP primer pairs. Primer Premier 6 will generate a list of SNP primer pairs and rank them according to their quality score. The quality score is based on several factors such as specificity, stability, and efficiency. You can also view the primer and probe sequences, their locations on the template, and their properties such as melting temperature, GC content, and self-complementarity.
Analyze the SNP primer properties and specificity. You can select a SNP primer pair and click on the Analyze button to see more details about the primer and probe properties, such as hairpin formation, dimer formation, and cross-dimer formation. You can also check the specificity of your primers and probes by performing a BLAST search against the NCBI database or a local database. This will help you avoid non-specific amplification and false negatives.
Manual primer search and editing
If you want to design primers manually or edit existing primers, you can follow these steps with Primer Premier 6:
Design primers by clicking on the template sequence. You can load your template sequence from NCBI or upload a FASTA file. You can then click on any nucleotide on the sequence to design a forward or reverse primer from that position. You can also drag your mouse over a region to select a primer.
Adjust the primer length and orientation. You can use the arrow keys or the mouse wheel to increase or decrease the primer length. You can also use the space bar to switch between forward and reverse orientation.
Edit the template sequence and remove unwanted regions. You can edit your template sequence by using the keyboard or the mouse. You can also remove unwanted regions from your template sequence by selecting them and pressing the delete key.
Pre-designed primer analysis
If you have pre-designed or published primers that you want to analyze for a template sequence, you can follow these steps with Primer Premier 6:
Analyze pre-designed or published primers for a template sequence. You can load your template sequence from NCBI or upload a FASTA file. You can then enter your pre-designed or published primers in the Primer box. Primer Premier 6 will analyze your primers for your template sequence and show you their properties and binding sites.
Check the primer orientation and binding sites. You can view the orientation of your primers (forward or reverse) and their binding sites on the template sequence. You can also see if your primers form a valid pair or not.
Allow mismatches and splice variants in primer analysis. You can adjust the number of mismatches allowed between your primers and your template sequence. This will help you find more potential binding sites for your primers. You can also allow splice variants in your primer analysis. This will help you detect alternative splicing events in your template sequence.
