IDT (Integrated DNA Technologies) have rolled out their £69 ($99) gBlocks - low cost synthetic DNA fragments of up to 500 bp in length that can be shipped in 3–4 working days for gene construction and modification.These are useful for production of short synthetic promoters and genes using Gibson Assembly. Error rates may be an issue for assembly of longer sequences, as average sequence fidelity of the gBlocks is around 90% - still potentially very useful.
