Primer designing for gene expression profiling (bacteria)
➢Get the gene name (eg: MYD88)
- Go to NCBI (ncbi.nlm.nih.gov), and search in ‘Gene’ for the gene sequence.
- Type in REL606 (that is the E.coli strain we use, unless stated otherwise) together with the gene name, and get the NM number of the most common transcript variant. (eg: NM_002468.4 for MYD88)
- Click on the link and go to the gene description page.
- Scroll down and clink on the link to find the CDS, or the RefSeq.
- Copy the CDS sequence.
- Go to the Primer 3 Plus website (http://www.bioinformatics.nl/cgi-bin/primer3plus/primer3plus.cgi) and paste the CDS sequence in the search box.
- All the parameters for optimal primers are usually preset. Do not change anything.
- Click “pick primers’.
- When the selection of primers comes up, choose a pair that is closest to the 3’ end.
- Check the primer is 20bp long and the product size is between 150-200bp.
- Blast to check the specificity of the primer pair (http://blast.ncbi.nlm.nih.gov/)
- Paste the forward and reverse primer sequences one by one and check if it gives a unique hit. (confirm chromosomal location of the gene from NCBI or other sources)
- If it gives multiple hits, select a different set of primers from Primer 3 Plus and repeat the same process until a unique set is obtained.
➢ Order primers through Invitrogen:
- Purification: Desalted
- Starting Synthesis Scale: 25nmole
- Ship Medium: Dry
- Normalization: None
- Calculate primers to 100uM using DNA suspension Buffer from Teknova cat # T0221
