Why do you use GeneArt® Strings™ DNA Fragments, and how have they impacted your research?
For the UC Davis 2014 iGEM project, we needed to screen a large number of enzymes for unique substrate specificities. GeneArt® Strings™ fragments made it extremely straightforward to order our desired genes and construct our expression plasmids with Gibson assembly. This allowed us to minimize the time between identifying enzyme sequences and experimentally characterizing these enzymes in the lab. Within the timeframe of an iGEM project, accelerating this process was extremely important to the success of our project!

What do you like best about GeneArt® Strings™ DNA Fragments?
My favorite aspect of GeneArt® Strings™ fragments is how convenient it is to customize and order DNA. The online project manager lets you modify genes by adding 3’ and 5’ cloning sites, protecting against certain restriction sites, and optimizing sequences for expression in different chassis. The project manager interface is extremely intuitive and makes ordering GeneArt® Strings™ fragments quick and painless.

What was your ordering experience like?
Ordering GeneArt® Strings™ fragments is quick and efficient. It takes only about 10 minutes to order genes, and they arrive a week later ready for cloning.

Have you used the online GeneArt® portal for gene optimization?
Yes, the online portal for gene optimization is extremely easy to use. Once you are finished specifying cloning sites and restriction sites to avoid, optimization is as simple as selecting your chassis in a dropdown menu. It takes less than a minute and your genes are optimized and ready to go!

Once you received your GeneArt® Strings™ DNA Fragments, were you ready to proceed to your experiment?
On the same day as receiving my GeneArt® Strings™ fragments, I use Gibson assembly to construct my plasmids and transform them into BLR strainEscherichia coli for enzyme expression.

Would you recommend GeneArt® Strings™ DNA Fragments to others?
Definitely!

Used GeneArt® Strings™ DNA Fragments for a 15-position alanine scan:

I just wanted to give you feedback regarding your tip with String synthesis for an Alanine Scan. I must say I am really enthusiastic. I cloned the 15 Strings directly without PCR amplification and then sent 6 clones each for sequencing. Nearly all clones where correct, that means that I could finalize all clonings within 1.5 weeks.

Why do you use GeneArt® Strings™ DNA Fragments?
Our goal is to express human proteins in E. coli to purify them and characterize them biochemically. My experience is that traditional methods (produce a cDNA, clone it, validate it, try to express it) are lengthy and inefficient especially given the challenges of suboptimal codon usage between human and E. coli. GeneArt® Strings™ fragments allow us to bypass all these steps and clone in an optimized gene fragment that is expression-ready.

How have GeneArt® Strings™ DNA Fragments impacted your research?
Strings™ fragments have permitted a tremendous gain in productivity.

What do you like best about GeneArt® Strings™ DNA Fragments?
Ordering a custom-built gene fragment is made so easy. And the quality of the product is fantastic. One can go from receiving a Strings™ fragment to expressing the protein in a matter of 2–3 days.

How do GeneArt® Strings™ DNA Fragments compare to similar products?
I have not tested other companies. And I’m not about to—Strings™ fragments offer everything I need at a good price.

What was your ordering experience like?
Very smooth, easy, user-friendly.

Have you used the online GeneArt® portal for gene optimization?
Yes, and it works incredibly well.

Once you received your GeneArt® Strings™ DNA Fragments, were you ready to proceed to your experiment?
Yes, the fragments were cloned in a matter of 2 days, and successful protein expression was obtained another 2 days later.

Would you recommend GeneArt® Strings™ DNA Fragments to others?
Absolutely. I can’t conceive of going back to traditional cloning myself, given the gains in productivity that Strings™ fragments afford you.

Zmapp Story

Mapp Biopharmaceutical was seeking to improve expression of several monoclonal antibodies that are part of their Ebola therapy ZMappTM. With GeneArt® gene optimization, antibody yield was substantially enhanced by testing different nucleotide variants of the heavy and light chain genes. Gene synthesis and subcloning services provided by GeneArt® led to speedy evaluation of these variants.

Numerous global pharmaceutical companies rely on GeneArt® gene optimization and gene synthesis for enhancement of their protein therapeutics, predominantly monoclonal antibodies in mammalian cells. The collaboration with Mapp Biopharmaceutical, which manufactures  ZMappTM in a relative of tobacco (Nicotiana benthamiana), proves that GeneArt® GeneOptimizer™ can also be used for plant expression.

Quote from Michael Pauly, CSO:  “The excellent web interface, ease of ordering, great customer support and improved protein expression all make GeneArt® an important part of our drug development pipeline.  We especially appreciate their willingness to respond very rapidly to our urgent requests for new reagents during the recent Ebola epidemic."

Why do you use GeneArt® Strings™ DNA Fragments?
Our goal is to express human proteins in E. coli to purify them and characterize them biochemically. My experience is that traditional methods (produce a cDNA, clone it, validate it, try to express it) are lengthy and inefficient especially given the challenges of suboptimal codon usage between human and E. coli. GeneArt® Strings™ fragments allow us to bypass all these steps and clone in an optimized gene fragment that is expression-ready.

How have GeneArt® Strings™ DNA Fragments impacted your research?
Strings™ fragments have permitted a tremendous gain in productivity.

What do you like best about GeneArt® Strings™ DNA Fragments?
Ordering a custom-built gene fragment is made so easy. And the quality of the product is fantastic. One can go from receiving a Strings™ fragment to expressing the protein in a matter of 2–3 days.

How do GeneArt® Strings™ DNA Fragments compare to similar products?
I have not tested other companies. And I’m not about to—Strings™ fragments offer everything I need at a good price.

What was your ordering experience like?
Very smooth, easy, user-friendly.

Have you used the online GeneArt® portal for gene optimization?
Yes, and it works incredibly well.

Once you received your GeneArt® Strings™ DNA Fragments, were you ready to proceed to your experiment?
Yes, the fragments were cloned in a matter of 2 days, and successful protein expression was obtained another 2 days later.

Would you recommend GeneArt® Strings™ DNA Fragments to others?
Absolutely. I can’t conceive of going back to traditional cloning myself, given the gains in productivity that Strings™ fragments afford you.

Other Quotes

Dr. Hans-Ulrich Schmoldt

BioNTech AG, Germany
Used GeneArt® Strings™ DNA Fragments for a 15-position alanine scan:

I just wanted to give you feedback regarding your tip with String synthesis for an Alanine Scan. I must say I am really enthusiastic. I cloned the 15 Strings directly without PCR amplification and then sent 6 clones each for sequencing. Nearly all clones where correct, that means that I could finalize all clonings within 1.5 weeks.

GeneArt® It… with GeneArt® Gene Synthesis and Optimization

Have you ever lacked the time to clone your favorite gene? You should consider gene synthesis, sometimes referred to as synthetic biology. Whether you need industry-leading gene synthesis services or optimized protein expression, or want to outsource the entire process to protein and cell line production, GeneArt® products and services can help you succeed.

Customer Stories

Zmapp Story

Mapp Biopharmaceutical was seeking to improve expression of several monoclonal antibodies that are part of their Ebola therapy ZMappTM. With GeneArt® gene optimization, antibody yield was substantially enhanced by testing different nucleotide variants of the heavy and light chain genes. Gene synthesis and subcloning services provided by GeneArt® led to speedy evaluation of these variants.

Numerous global pharmaceutical companies rely on GeneArt® gene optimization and gene synthesis for enhancement of their protein therapeutics, predominantly monoclonal antibodies in mammalian cells. The collaboration with Mapp Biopharmaceutical, which manufactures  ZMappTM in a relative of tobacco (Nicotiana benthamiana), proves that GeneArt® GeneOptimizer™ can also be used for plant expression.

Quote from Michael Pauly, CSO:  “The excellent web interface, ease of ordering, great customer support and improved protein expression all make GeneArt® an important part of our drug development pipeline.  We especially appreciate their willingness to respond very rapidly to our urgent requests for new reagents during the recent Ebola epidemic."
