![]() In our lab, we have successfully used this procedure to generate several mutations at the SCH9 locus, encompassing full gene knockout, deletion of specific gene regions, and domain replacement ( Novarina et al., 2021), as well as to perform gene knockouts and to introduce point mutations in several yeast genes ( Guerra et al., 2021). After verification of the genome editing event(s) by PCR and/or Sanger sequencing, the Cas9+sgRNA(s) multi-gene plasmid is removed from yeast cells. Co-transformation of the Cas9+sgRNA(s) multi-gene plasmid and the repair fragment(s) in yeast results in CRISPR genome editing. One or two sgRNA are cloned in a yeast expression vector together with the Cas9 gene through three consecutive Golden Gate assembly reactions ( Engler et al., 2008 Lee et al., 2015) ( Figure 1). We provide detailed instructions for choosing the sgRNAs and designing partially overlapping complementary oligos for sgRNA cloning, as well as for the design and production of the repair fragments, depending on the nature of the desired genome editing event. In addition to SnapGene, GSL Biotech offers the free SnapGene Viewer, which includes the key visualization tools of SnapGene and allows researchers to make DNA maps and design primers, as well as SnapGene Server, which allows interactive DNA maps to be displayed in a web browser.This protocol describes a detailed procedure to perform CRISPR/Cas9 genome editing ( Doudna and Charpentier, 2014) in S. cerevisiae, based on the MoClo-Yeast Toolkit ( Lee et al., 2015) and a pre-existing protocol ( Akhmetov et al., 2018). Free trials of the software are available from the SnapGene website. The software provides a simple yet powerful way for researchers to plan, visualize, document, and share their everyday molecular biology procedures. GSL's SnapGene desktop software ( ) is used in virtually every major research institution, and in more than half of the largest pharmaceutical and biotech companies worldwide. GSL Biotech was founded by scientists and software designers to meet the everyday needs of molecular biologists. By authenticating, storing, archiving, and distributing plasmids, virus, and their associated data, Addgene is creating a lasting resource for research and discovery scientists around the world. Addgene also provides ready-to-use AAV and lentivirus preparations of commonly requested plasmids as a service to scientists - saving them time and providing thorough quality control. Over a half million plasmids have been distributed to more than 90 countries by Addgene - with 11,000 plasmids currently shipping each month. The repository contains over 53,000 plasmids contributed by 3,300 research labs around the world. Both companies are dedicated to improving data accessibility and look forward to further enabling scientists through this fruitful collaboration.Īddgene is a 501(c)3 nonprofit biorepository dedicated to facilitating scientific discoveries by operating a plasmid library for researchers. We’re pleased that Addgene runs SnapGene for their internal use, and delighted that Addgene customers will now have easy access to those visualization tools on .”Īddgene and GSL Biotech will continue to work together in the coming months to build out the plasmid sequence analysis tools available at. Our company was founded by scientists who share Addgene’s vision to make science move faster, and clean, accurate plasmid visualization is part of that equation. “Addgene provides a wonderful service to the research community, and we’re proud that our customers around the world have been contributing to Addgene’s plasmid collection for many years. “GSL Biotech is thrilled to partner with Addgene on this project,” said Aline Glick, VP of Product Management at GSL Biotech. We hope the SnapGene powered plasmid maps and sequence displays will greatly improve user experiences on our website.” “Giving our users the ability to identify which of the plasmids in the repository have the features they need for their upcoming experiments will enable them to complete their experiments faster and accelerate their research. “Addgene is excited to work with GSL Biotech and their SnapGene Server software,” said Joanne Kamens, Executive Director of Addgene. dna format, which can be read by the free SnapGene Viewer program. Additionally, the software gives users the ability to download sequence files in GenBank format and also in SnapGene’s. The new maps will annotate common plasmid features, such as resistance genes, tags, and Cas9, based on SnapGene’s extensive feature library. These updates allow Addgene users to quickly analyze plasmid features through easy-to-read interfaces. Addgene, a nonprofit plasmid repository dedicated to sharing plasmids and accelerating research, announced today that plasmid map and sequence displays on their website will be powered by GSL Biotech’s SnapGene Server software. ![]()
