Plasmids 101: Fluorescent Biosensors

Posted by Jessica Welch on May 18, 2017 10:30:00 AM

Addgenie Mary Gearing contributed to the content of this article.

Biosensors (‘biological sensors’) are biological tools that monitor a process or detect a given molecule. The sensor component is usually a protein that undergoes a conformational change in response to the molecule it detects. This change then generates a reporter signal. Reporter signals may be electrochemical or light-based, with luminescent and fluorescent reporters being especially popular. We’ll give you an introduction to fluorescent biosensors, but keep in mind that there is a lot of variety in how biosensors work, and you should always check the associated publication for the specifics of your chosen plasmid.

Plasmids 101: Environmental Plasmids

Posted by Jessica Welch on Jan 31, 2017 10:30:00 AM

Here at Addgene, we often refer to plasmids as lab or experimental tools. They certainly are very handy in research, but where did these tools come from and why do they exist in nature? Read on to learn more about environmental plasmids, and how they’ve helped us develop molecular biology tools for the lab.

Addgene at the ASM Microbe 2016 Conference

Posted by Jessica Welch on Jul 7, 2016 10:30:00 AM

We’ve recently begun expanding our presence in the microbiology community. For our first concrete steps into this field, we’ve curated microbiology plasmids from the repository onto one handy Microbiology Resource page and, just a few weeks ago, we attended the American Society for Microbiology's annual meeting (ASM Microbe 2016) for the first time. Our goals at the meeting were to network with scientists in this diverse and exciting field and to find out how we can serve them better. Here’s a little bit of what we learned.

Introducing Addgene's Microbiology Pages

Posted by Jessica Welch on Jun 13, 2016 3:08:05 PM

Addgene will be at the American Society for Microbiology Microbe meeting here in Boston next week - be sure to come by booth #851 and say hello! Just in time for this meeting, Addgene is launching a new resource page for the Microbiology community. On our new curated Microbiology Collection page, you can browse for plasmids by species and find our guides, plasmid kits and other resources for microbial research.
