How to Cheat QuikChange™

Generating a DNA vector library of single and/or compound mutants for a target protein can be a daunting task. If you’re lucky and work in a well-funded lab, you might outsource this process via gene synthesis. Most of us though, need to do it the old-fashioned way. Traditional QuikChange™ Traditionally, there are many steps you…

Gene Synthesis: Cloning of The Future?

I remember the time when elves and wizards walked the Earth and DNA oligonucleotide synthesis was $5 a nucleotide. But the world has changed, nobody thinks twice about ordering an oligo. Whole gene synthesis, which is synthesis of long oligos and their assembly into a very, very long oligo. With prices of around 25–35 cents per…

Codon Usage Analysis

Problems with expressing your gene? One of the potential stumbling blocks in heterologous gene expression is incompatible codon usage. Every amino acid can be encoded by more than one codon, and for every amino acid each organism has a favorite codon that it tends to use more often than the others. The availability of tRNA…

Custom Gene Synthesis: A PCR alternative.

Artificial gene synthesis was first reported in 1972 when a group of researchers at Massachusetts Institute of Technology synthesized a complete yeast alanine tRNA gene. Synthesis of the first peptide- and protein-encoding genes ensued in the following decade. Since then, synthetic biology has advanced in leaps and bounds, and custom gene synthesis, a one-time expensive option for…
