Evotec SE, Germany
VectorBuilder is the best platform for designing and synthesizing constructs. The online vector design tool is so convenient and fun to use. Ms. Joyce Zhang is always very professional in replying my questions and does it so timely. One time, something did not work out, the refund process was smooth and all the staff were very nice and professional. The constructs I asked for had two fluorescent proteins with two promotors, one has NLS and the other does not. I did transfection and it worked out very well. Joyce helped me all through this process, making my life very easy. Basically, I had many pleasant experiences with Vectorbuilder, and I strongly recommend using it. I had tried other companies, they turned out to be either slow or lacked strong technical support or are expensive. Vectorbuilder is not the cheapest, but considering the quality of its service, it is worth the money.

I have been using ready-to-use lentiviruses from Vectorbuilder and they are working great. I used them against iPSC-derived neurons, and the transduction and expression of transgenes are remarkable. The vector backbones provide multiple options to tag your GOIs with fluorescent proteins or implement antibiotic selection markers. Their vector designing tools are helpful. Customer service is reliable. Good luck!
University of California San Diego, USA
VectorBuilder is an amazing way to save time normally dedicated to molecular biology. The website is easy to use, well-conceived and allows quick design in most cases. For more unusual requests, the team is energetic, reply promptly on every request, and always finds a way to help. Low prices and short timelines really make it possible to consider VectorBuilder for many cloning matters.

I recently met one of the VectorBuilder product specialist during AAI-2019 meeting at San Diego Convention Center. Her name is Dr. Swati Ray, and she provided me excellent information regarding their products and vector designs. And then, we recently purchased CRISPR Cas9 dual gRNA vector. Now, we are ordering few more plasmid vectors. As per my experiences, VectorBuilder customer services are excellent and user-friendly. The VectorBuilder product prices are reasonable.
UT Southwestern Medical Center, USA
Vectorbuilder's service is extremely consistent. We started with regular plasmids and AAV plasmids. Since last year we have ordered many piggybac plasmids. All worked as expected.
Janelia Research Campus, USA
We began using VectorBuilder for adenoviral plasmids construction about a year ago. We normally handled all cloning projects ourselves, but when it comes to adenoviral vectors, because of their large size, sometimes the cloning is kind of tricky for inexperienced students. So we decided to give VectorBuilder a try. The plasmid arrived one month later and the virus we generated from it expressed the correct gene. We have ordered more than 10 adenoviral plasmids and they all work fine. VectorBuilder has saved us a lot of time.
DUKE-NUS Graduate Medical School, Singapore
I’ve been using VectorBuilder’s virus packaging services for two years. Their viruses worked well and my projects are going on well. I’ve published two papers on SCI journals using VectorBuilder’s services. Thank you, VectorBuilder!

I would like to share with you my positive experience purchasing a lentiviral vector from VectorBuilder.
First, I am an immunologist and have little experience with cloning. In my recent project, we needed to overexpress a gene in melanoma cells. The transfection efficiency using plasmids in this cell line was extremely low, less than 10%. Then, we tried to use antibiotics to select transfected cells and establish stably expressing cell lines. Unfortunately, for unknown reasons, the ‘stable transfectants’ lost the transfected genes! I was frustrated at this
point,until I met VectorBuilder at the EACR conference in Amsterdam. Using the user-friendly website from VectorBuilder, I designed for the first time in my life my own lentiviral vector and got the product in less than one month. My group leader, who has a lot of cloning experience, could not believe that it worked so quickly. Of course, most important are the experimental results. To access the transduction efficiency, I included an EGFP tag in the vector. Now, I can transduce the melanoma cells with nearly 100% positivity. In the following assays, the genes transduced into the tumor cells resulted in a 6-fold induction in tumor immunogenicity.
Taken together, I strongly recommend VectorBuilder to researchers, especially those who are not so experienced with
cloning,and am convinced that the service and product quality from VectorBuilder can further help me to proceed with my own projects more effectively.
I have been consistently using VectorBuilder over the last couple of years and have been extremely satisfied with the vectors they've delivered. These include standard over-expression vectors, and Cas9 vectors on the PiggyBac backbone. All of the vectors I have purchased so far have passed my QC and provided reproducible functional data.
Vancouver Prostate Centre, Canada
VectorBuilder did vector construction and lentivirus packaging for my shRNA knockdown experiment. The transduction efficiency of the lentivirus was high. Their staff were very considerate, and related technical questions were addressed quickly. I’ve finished many experiments and I’m preparing the manuscript for submission.
School of Nature Conservation, Beijing Forestry University, China
Amazing experience with VectorBuilder! I ordered plasmids at the beginning of December, and despite the holiday
seasonthey arrived exactly as scheduled. Furthermore, customer support reached out to ask what would be my desired delivery date, considering potential holiday conflicts at my institute. Overall, I am very satisfied, would highly recommend VectorBuilder (which I already do) and will buy from them again. All the best from my side!

The First Affiliated Hospital of Guangzhou Medical University, China
We recently purchased a number of customized plasmids on VectorBuilder. They consisted of expression vectors of two or more ORFs. Our experience was satisfactory, efficient and cost-effective.
The designing stage was facilitated by the VectorBuilder design tool online, in which many of the most commonly used sequences, like fluorescent proteins, selection drug resistance genes, and fusion or cleavage linkers were readily offered to be picked from the ORF lists. Regarding our specific sequences, once pasted into the corresponding window of the design tool, they were immediately matched with the International Nucleotide Sequence Database Collaboration (DDBJ/EMBL/GenBank) accession numbers and compared to the databases. Where there were discrepancies, we were asked which transcripts/cDNAs we preferred to use.
After completing the order, in a matter of three to four weeks, we had in our hands 8 of the 10 plasmids, as offered. For the rest of the
plasmidswe provided the template for a specific sequence. Before proceeding with the cloning, they sequenced it, detected a mutation and corrected it at a low extra cost upon our approval. A week later these corrected plasmids were delivered as well. During the whole process, VectorBuilder’s European team kept a personalized email dialogue with us, enabling us to follow-up and make decisions or accept suggestions about the plasmids.
We have satisfactorily tested every plasmid now. We think that our decision to work with VectorBuilder has boosted our research by saving us time, resources and enabling us to concentrate more on our experiments.

The University of Manchester, UK
We were searching for a way to outsource the cloning of our vectors and we are very happy with the service. The versatility of the tools make it a great time saver and the vectors were delivered on-time. Lentiviruses packaged are also very reliable and have been very successful in transduction studies in primary cells. Great customer service with fast response times and the team at VectorBuilder are very knowledgeable.
Aridis Pharmaceuticals, USA
I have been successfully cloning for 3+ years, but the last time we tried generating KO cell lines with CRISPR/Cas9 vectors, we were not successful. This was upsetting, especially since I invested a lot of time in these efforts. Then, by chance, I attended one of VectorBuilder's seminars. Due to their reasonable prices and the fact I could focus my time on other work, we decided to give their lentiviral (dual gRNA) Cas9 plasmid a try. The turnaround time was reasonable, their customer service was excellent and they actually gave feedback about the status of my cloning projects. Their website is also easy to use. But most importantly: using their Cas9 dual
gRNAvector, I was able to successfully generate KO cell lines!
I recommend VectorBuilder to CRISPRCas9 users without any hesitation.
Anna Salamero Boix
Georg-Speyer-Haus Frankfurt, Germany
We have ordered several vectors from VectorBuilder, including regular expression plasmids, targeting vectors and AAVs. The constructs were delivered on time and worked very well. They saved us a lot of time and money. Their design team pays attention to detail and made very useful suggestions. Their customer service is excellent as well. Overall, we highly recommend VectorBuilder.
