Quick Guide to Working with Drosophila Part 1: Getting Started with Flies

Posted by Guest Blogger on Jul 13, 2017 10:30:00 AM

This post was contributed by guest blogger Jon Chow, an immunology PhD student at Harvard University.

Do you have a gene of interest but have run into a wall trying to study it? It happens. Is it an evolutionarily conserved gene? Can you find an ortholog in the Drosophila genome? Continue reading and I’ll show you how Drosophila can be used to push your research in new and exciting directions.

Drosophila are very easy to manipulate genetically and have limited genetic redundancy (meaning, there’s more of a chance of seeing a phenotype since additional genes that can do the same function are less likely to exist). If there’s an ortholog of your favorite gene (YFG) in Drosophila (and even if there’s not!) the wealth of Drosophila genetic tools available allow you to study many aspects of your gene’s functional biology in a living organism. This is the first post in a three-part series. We’ll first discuss how to get started on fly work in this post. The second post will detail a major tool used by Drosophila geneticists (the Gal4/UAS system), and the third post will describe how you can make your own mutant flies.

How to Design Your gRNA for CRISPR Genome Editing

Posted by Guest Blogger on May 3, 2017 11:00:00 AM

This Post was updated on May 3, 2017 with additional information and resources. 

This post was contributed by guest blogger, Addgene Advisory Board member, and Associate Director of the Genetic Perturbation Platform at the Broad Institute, John Doench.

CRISPR technology has made it easier than ever both to engineer specific DNA edits and to perform functional screens to identify genes involved in a phenotype of interest. This blog post will discuss differences between these approaches, as well as provide updates on how best to design gRNAs. You can also find validated gRNAs for your next experiment in Addgene's Validated gRNA Sequence Datatable.

5 Great Apps for Lab Life

Posted by Guest Blogger on Sep 22, 2016 10:30:00 AM

This post was contributed by guest blogger Sean D. Stacey. Opinions on the apps discussed in the article are those of the guest blogger and do not necessarily represent the views of Addgene.

I think it’s safe to assume that anyone reading this article has a smartphone nearby. We tailor these devices to our own interests with the content we store in them: music, emails, chats, pictures, and apps. Throughout my time as a graduate student, I have relied more and more heavily on adapting my smartphone to help me with my research in terms of preparedness, organization, and sharing data. Here are five FREE science lab apps that have been educational and great for lab life. These apps prevent you from constantly searching the interwebs for lab resources, and instead conveniently provide them on your smart phone.

Tips for Technical Support Calls

Posted by Eric J. Perkins on Sep 20, 2016 10:39:02 AM

I’ve answered hundreds of phone calls and thousands of customer service emails in my six years as a senior scientist at Addgene. Having spent that long in customer service, I've daydreamed about the ideal customer service interaction - one that gives our customers the most utility in the least amount of time. Though I now spend far less time answering help emails and phone calls, I feel compelled to share my years of accumulated wisdom so that you, the customer, can get the most out of your email or phone call. Though my experience is based solely on my time at Addgene, I’m confident that these tips and tricks will apply to any biology-related customer support interaction.
