Plasmids 101: Screening Strategies Used in Plasmid Cloning

Posted by Jennifer Tsang on Sep 15, 2020 9:15:00 AM

If you’re cloning a plasmid, you’ll need a way to find the needle in the haystack: the one perfect clone that contains the plasmid you’re looking for out of the many cells that don’t. One way to begin the search is by using selection strategies, where only cells that have gained or lost a specific gene survive (ex: antibiotic resistance marker). In a previous blog post, we covered how to use positive and negative selection in plasmid cloning

Supporting Rare Disease Research with the 2020 BeHEARD Awards

Posted by Jennifer Tsang on Sep 8, 2020 10:00:00 AM

The Rare Genomics Institute BeHEARD (Helping Empower and Accelerate Research Discoveries) Challenge provides grants for rare disease research. This year is our fourth year working with the Rare Genomics Institute by providing plasmid-based tools for rare disease research.

Congratulations to the winners! Below, we highlight their research and how they will use plasmids and viral preps from Addgene to further their work.

Quantifying DNA? Here are Five DNA Quantification Methods to Consider

Posted by Jennifer Tsang on Jul 21, 2020 9:15:00 AM

You’ve prepped your DNA and you’re ready to get started on the next step of your experiment. But in many cases, you won’t see any signs of DNA in your final tube after purification. How do you know if you actually have DNA in your tube without seeing it?

There are many ways to do this and the method you choose could be based on your downstream application, time, and instrument availability.

Virtual Science Conference Coming Up? Three Addgenies Share Their Experience

Posted by Jennifer Tsang on Jun 30, 2020 9:15:00 AM

As with many aspects of our lives that have gone virtual, scientific conferences have followed suit. Two Addgenies, Susanna Bachle and Yijun Zhang, recently attended virtual conferences (TAGC and ASGCT, respectively) and Addgenie Angela Abitua hosted a virtual Reproducibility for Everyone workshop at TAGC with the three other organizers. We asked them about their experiences as they navigate the new norm in scientific conferences.

Sharing Plasmids Globally for COVID-19 Research

Posted by Jennifer Tsang on Apr 30, 2020 9:15:00 AM

In the past few weeks, we’ve received over 2,600 COVID19 related plasmid requests. These plasmids have been heading to research labs in 43 countries.

COVID-19 research is happening fast and we’re glad to join these efforts and help scientists through plasmid sharing and more. These include plasmids that have been in the repository for many years, and new plasmids that scientists have deposited in the last several weeks. We've grown the collection of COVID-19 related plasmids to over 500 plasmids and our mission to accelerate research through sharing reagents has never been so important as scientists work around the clock to find solutions for COVID-19. Sharing speeds science.
