that required synthesis of some relatively long DNA molecules (up to 2.4 kb) as well as some shorter molecules entirely composed of nearly perfect repeats and molecules with origins of replication. Mr. Gene was up to the challenge. Besides, no other company was able to give us comparable price. Marvelous job!

Very swift response times and a high degree of flexibility make it stand out in the biotech sector. All this on top of effortless cloning and codon optimization thanks to DNA synthesis make this service worth every penny

I needed a series of small genes and cloning them our self would have been a hassle and a lot more expensive than Mr. Gene’s flat rate for small genes. The web page interface for ordering is intuitive to use and makes ordering very simple.

I needed to construct a multidomain molecule from 8 different genes. Compared to PCR assembly, Mr Gene synthesis eliminated months of work and saved money too. I will come back again and again for all of my complex cloning projects in the future. Thank you Mr Gene!

for vector modifications that couldn't be provided by the standard oligo manufacturers. The service of Mr. Gene was what I was looking for. Mr. Gene helped me to find a solution at a very competitive cost. Two Thumbs up!

customer service. They complete the synthesis of DNA sequence in a very speedy fashion. The cost is very competitive. I am very pleased with our past order and I and the rest of our group will come back for future ordering.

the services of Mr. Gene, fast and cheapest source for synthetic genes. In academic institutes, we do our own codon optimization but gene synthesis cost is very important factor due to limited budget. Mr. Gene maintains reliability and a good cost-value ratio. Gene ordering is done online in a few minutes.

has made us loyal costumers; it is the first company that was able to reliably and quickly synthesize DNA sequences that are both highly repetitive and self-complementary, all while maintaining competitive pricing.

and Mr. Gene did a great job in simplifying the sequences and synthesizing the optimized genes. Other vendors were either unable to simplify the sequences, or charged a lot more than Mr. Gene.

was prepared by Mr Gene while other companies refused to synthesize the gene due to a very high GC content.

for me to use gene synthesis. I needed codon optimization because as structural biologist I am aiming for high expression levels. And indeed: The gene performed well - expression levels in E.coli are very good. In addition, Mr. Gene's website is so easy to use. I didn't think that cloning could be so simple!

that codon optimization can boost protein expression that much. Thanks to Mr. Gene’s optimized sequence we save a lot of time and money during protein expression and purification. The online step-by-step process made it easy to design, optimize and order my gene without waiting. This is perfect when you want to get started.

to have this fast open access source for synthetic genes. For most genes needed in research, reliability and a good cost-value ratio is important. Gene optimization and ordering is done online in a self explaining way in a few minutes.
