13 Aug 15. What is the difference between a long oligo and a synthetic gene?
Due to limitations in oligo synthesis chemistry and other practical considerations, oligos are produced as mixture of single-stranded DNA strands and are limited in length to ~200 bases.
Synthetic genes can extend to several thousand, double-stranded base pairs. Usually created as a sequence verified clone, the products from these constructs may be the best tool for your research needs.
