I purchased lentivirus vector and received it in less than two weeks after I placed the order. I am so glad that I found vectorbuilder, so I can design it with any promotor, and antibiotics selection and any tag into my lentivirus vector. The target gens high expressed in several cell lines after I did transduction, and stable cells expressed very strong at least after one month since I did selection.

I have been successfully cloning for 3+ years, but the last time I 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
chanceI attended toone of the seminars of VectorBuilder. 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 really gave feedback about the status of the cloning. 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.

We recently purchased from VectorBuilder a lentiviral plasmid for constitutive expression of GFP and luciferase and the corresponding lentivirus. We had infected several tumor cell lines with excellent results. The lentiviral stocks worked very nice saving us a lot of time. We are now using these modified cell lines for monitoring tumor growth in animal models using in vivo imaging.

I’ve been using VectorBuilder’s virus packaging services for two years. The virus worked well and my projects are going on well. I’ve published two papers on SCI journals using VectorBuilder’s services. Thank you, VectorBuilder!
Zhejiang University, China
We began to use VectorBuilder to prepare adenoviral plasmids about a year ago. We normally handled all the cloning stuffs ourselves, but when it comes to adenoviral vectors, because of its large size, sometimes it is kind of tricky for inexperienced students. We decided to give a try on VectorBuilder. One month later, the plasmid arrived and it generated virus that expressed the correct gene. After that, we have ordered more than 10 adenoviral plasmids and they all work fine. VectorBuilder did save us a lot of time.
DUKE-NUS Graduate Medical School, Singapore
VectorBuilder’s service makes designing vectors incredibly simple and there’s no software required, it can all be done through their easy to use website. The lentivirus production service is a massive bonus as it’s so quick and reasonably priced there’s really no reason to make our own lentivirus anymore. Thanks for a fantastic service.

I’ve always been using VectorBuilder’s vector construction service. I’m generally satisfied with the quality of its service, and the problems I encountered were solved quickly.
The First Affiliated Hospital, Sun Yat-sen University, China
Amazing experience with VectorBuilder! Ordered plasmids 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 time at my institute. Overall, I am super satisfied, would highly recommend VectorBuilder (which I already do) and will buy from them again. All the best from my side!

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 stable transfectants. 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 fast. Of course, most important are the experimental results. To access the transduction efficiency, I built an EGFP fragment 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 ordered a plasmid vector two years ago. The design on the web platform was easy. Contacts with the specialists to arrange further details were excellent: they are very supportive!
Consiglio Nazionale delle Ricerche, Italy
VectorBuilder did vector construction and lentivirus packaging for my shRNA knockdown experiment. The transduction efficiency of the lentivirus was high. Their staffs were very considerate, and related technical questions were addressed quickly. I’ve finished many experiments and I’m preparing the manuscript for submission.

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 offered. 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. Upon discrepancies, we were asked which one 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 processthe VectorBuilder’s European team kept a personalized dialogue per e-mail 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

We have ordered quite a few plasmids from VectorBuilder in the past 1-2 years, ranging from regular plasmids, piggybac, and AAV vectors. The products have been delivered on time and worked as expected. Highly recommend!
Janelia Research Campus of Howard Hughes Medical Institute, USA
I’ve used VectorBuilder’s lentivirus packaging service. The virus titer was as promised. Strong fluorescence was observed after transduction. The gene knockdown efficiency was satisfied.
Southern Medical University, China
VectorBuilder is an intuitive tool to help your need in developing vectors at an affordable price. I was in need of a CRISPR Lentiviral system with a Puro selection due to working with delicate cells that cannot handle FACS sorting pressures. With their online interface, it was easy to construct the vector I wanted and received the vector in a timely manner! It was simple to produce virus and test it in our cell culture and had good knockdown clones. I definitely will be ordering more vectors from
Cyagento finish up my thesis!
University of Colorado, USA
We ordered adenovirus from VectorBuilder to overexpress our protein of interest in primary mouse hepatocytes. The ordering process, including vector design, was very fast and easy. We received the plasmid and adenovirus within the time frame that was stated during the ordering process and the transduction efficiency of the adenovirus was very high, enabling us to use a low MOI. As a bonus, we also received the control Ad-EGFP adenovirus for free. In the future, I will not use any more siRNA or classical transfection methods on primary mouse hepatocytes, just adenoviruses from VB! I can highly recommend VectorBuilder's services for vector design and adenovirus production.

I’ve used VectorBuilder’s vector construction and lentivirus packaging services. The turnaround time was short and everything worked well. Also, I got quick response from the customer support team.
Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University, China
I have been consistently using VectorBuilder over the last couple years and have been extremely satisfied with the vectors delivered to me. These include standard over-expression vectors, and Cas9 vectors on piggybac backbone. All of the vectors I have purchased so far have passed my QC and provided reproducible functional data.
Vancouver Prostate Centre, Canada
We applied CRISPR cas9 nickase in our study. VectorBuilder helps us to design the gRNAs and construct the plasmid with double gRNAs and double selection markers (EGFP/puromycin). The gRNA specificity is quite good, better than available online design tools. We got the knockout cell lines in the first run of electroporation with no off-target event. I would recommend VectorBuilder to CRISPR cas9 users.
