Twist Bioscience Clonal-Ready Gene Fragments

Twist Bioscience has launched clonal-ready gene fragments. The synthetic DNA products are available with and without adapters and can be used to build constructs. Potential applications include cloning, gene and protein expression, pathway and enzyme engineering, and enzyme optimization.

Gene fragments begin as oligonucleotides, are annealed, and amplified to produce double-stranded DNA fragments. They are error-corrected in an enzymatic reaction. The error rate is 1 in 5,300 base pairs; for shorter oligonucleotides between 300 and 800 base pairs long, the error rate drops to 1 in 6,200.
