I have used several other companies for gene fragments in the past, and one issue I frequently encountered was minimum order requirements. I would often have to purchase more fragments than I actually needed, which made the overall order unnecessarily expensive. Other companies that avoid these minimums can also be quite costly. When I tried Twist Bioscience, I was pleasantly surprised by how easy the website was to navigate and how straightforward the ordering process was. Most importantly, I could order the number of fragments I actually needed without being forced to spend significantly more. I was also really impressed by the cloning efficiency. I have rarely seen such consistent colony growth and colony sizes. Using the same cloning and miniprep protocols I normally use, I consistently obtained high plasmid yields, often around 500 ng/µL, with A260/280 ratios around 1.8 across my samples. The resulting plasmids have also performed very well for AAV production, yielding high viral titers. The protocols on my end have not changed; the main difference was using Twist Bioscience for the DNA synthesis. Based on my experience, I would recommend Twist to both people who are learning molecular cloning and experienced researchers looking for a reliable and convenient option. Thanks for Twist Bioscience, we are advancing human neuroscience to a new level!

Twist is great, reasonably priced and fast. However, I think they should improve pricing on fragments cloned in a plasmid for long sequences/large protein expression vectors and allow for the synthesis of more complex DNA. I often have to adjust my sequences several times before their algorithm accepts it.

Twist's service is, as always, unparalleled in providing high-quality DNA synthesis in record time to my location. The tools provided by Twist for designing and optimizing the DNA constructs, and their customer service, are great for preparing both the order and the downstream experiments, leading to a high number of transformants in very few experiments. It's always a seamless, easy-going experience to use Twist's products, and one that I recommend every time a colleague is searching for DNA synthesis providers.

I had a great experience with Twist Bioscience. I ordered gene fragments and later realized that I had made mistakes in the sequences I submitted. Even though the fragments had already been delivered months earlier, the team was incredibly helpful and worked with me to fix the issue and reorder the corrected fragments. Everyone I interacted with was kind, easy to talk to, and genuinely took the time to listen to my concerns. The reordered sequences worked perfectly, and I was able to continue my work without further issues. I really appreciated the level of customer support and care they provided, especially given that the original mistake was on my end. I would definitely recommend Twist Bioscience for gene fragment synthesis.

Twist has a very easy to use web system for screening gene sequences for complexity and quick and easy steps to submit orders online. No fuss account set up- I really appreciated it. They were extremely accommodating in expediting the gene synthesis process and timely delivery. Thank you for such an amazing service.
