Rules to design good primers
WebbPrimer design tips. In general, a length of 18–30 nucleotides for primers is good. Try to make the melting temperature (T m) of the primers between 65°C and 75°C, and within 5°C of each other.; If the T m of your primer is very low, try to find a sequence with more GC content, or extend the length of the primer a little.; Aim for the GC content to be between … Webb14 maj 2012 · Guidelines for Primer Design G1. Primer length should be in the range of 18 to 22 bases. Primers less than 18 bases will have a low melting temperature (Tm values) and might not anneal to the template. There is some flexibility for …

Webb25 mars 2013 · As a rule of thumb, the Tm of the primers can be estimated by adding 2°C for each A or T and 4°C for each G or C. The Tm of a nucleic-acid duplex increases both with its length and with increasing GC content. Make sure the Tm difference of your custom primers is no more than 5°C between the pair.
