Using double coupling to improve your peptide synthesis
There are several strategies employed when a peptide synthesis requires optimization. Typically, the first thing considered is whether or not to double couple specific amino acids within the sequence. This is somewhat of a change in mentality from traditional room temperature synthesis strategies where double coupling is frequently used for the entire peptide sequence.
In a previous post, I briefly described several scenarios in which doubling coupling can be used in conjunction with microwave heating to improve the overall crude peptide purity. In today’s post, I will delve more deeply into the question of whether or not double coupling is necessary to improve your peptide synthesis.
