No Long Runs With The Same Base
Home > DNA Amplification > Overview > Primer Design > No Long Runs With The Same Base
Primers with long runs of a single base (more than three) should generally be avoided as it can cause breathing of the primer and aid in mispriming. For example, the sequence AGCGGGGGATGGGT has run of five for the base G.
