I needed to synthesize highly repetitive sequences

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.

This synthetic gene

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

This was the first time

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!

I never expected

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.

It is wonderful

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.
