- DATA
Twist’s DNA synthesis technology outperforms the competition with exceptionally low error rates.
In a direct comparison of Gene Fragment products, Twist consistently showed the lowest error rate. The graph to the left represents the average error rate for Gene sequences ordered from Twist and Integrated DNA Technologies, Inc. (IDT). The results show Twist Gene Fragments have greater sequence accuracy over eBlocks and gBlocks with an average of 2-fold greater accuracy in sequence fidelity for Twist Gene Fragments over gBlocks.
More perfect Genes from Twist
Twist Gene Fragments consistently yield the highest percentage of perfect clones which saves you time and money in your research. The graph to the left shows a direct comparison of the percentage of sequence-perfect clones across a wide variety of gene lengths and sequences for 3 different gene products. Data was generated using a set of 63 sequences with a wide variety of gene lengths to reflect the diversity of gene lengths required for various real-world synthetic biology applications.

FAQ
What is the price for a gene fragment?
The price of a gene fragment will vary based on the size of the fragment. Fragments can be ordered with or without adapters.
What methods can I use to clone my adapter-on gene fragments?
You can use the following methods to clone gene fragments with adapters:
Restriction digestion/Ligation - place restriction sites inside of the Twist adapters for easy cloning
Type IIS or Golden Gate - place restriction sites inside of the Twist adapters for easy cloning TOPO cloning (blunt-end) - the adapter sequences will be cloned in as well
Gateway cloning - add attB sites to the ends of your sequence
Are adapter sequences appended onto the ends of my sequences?
For Adapter-On Gene Fragments, universal adapters are synthesized onto the ends of each fragment. The adapters are 21-22 nucleotides in length. Fragments with these adapters are compatible with a number of assembly methods, namely Restriction Digestion/Ligation, Gateway, Golden Gate, and TOPO cloning.
The addition of restriction sites inside of the adapters can be used to remove adapters. TOPO cloning will work but will leave the adapters on.

*Adapters are short sequences added to each end of the insert as part of our synthesis process. Gene fragments without these adapters are also available during the checkout process.
Are Gene Fragments Purified?
Yes, gene fragments go through a bead-based clean up; however, short fragments can carry over in small quantities.
