This post was contributed by guest blogger Katrin Michel. Cre-lox is an incredibly popular and powerful site specific recombinase (SSR) system, but it only gives you a single level of control without modification - either Cre is there or it’s not. Cre-mediated possibilities for ...
One of the most powerful strategies to investigate a gene's function is to inactivate, or "knockout", the gene by replacing it or disrupting it with an piece of DNA designed in the lab. Specially constructed plasmids can be used to replace genes in yeast, mice, or Drosophila ...
In a previous post from our Plasmids 101 series, we learned how the Cre-loxP recombination system can be used to induce site-specific recombination events, and that the orientation of the flanking loxP sites directs the Cre recombinase to invert, translocate, or excise a DNA ...
At Addgene, we love GFP, and we’re always excited when depositors find new ways to make this workhorse protein even more useful! From FPs optimized for oxidizing environments to photoconvertible variants, it seems like GFP is always learning new things. Now, work from Connie ...
Cre-lox recombination is an incredibly useful molecular biology tool, but like any biological system, it has certain drawbacks. First, the efficiency of Cre recombination varies for different constructs and cell types. Second, Cre may induce recombination at pseudo- or cryptic ...
In previous posts for our Plasmids 101 series, we examined a number of important plasmid elements – promoters, origins of replication, protein tags, and antibiotic resistance markers (just to name a few). In this edition, we’re going to take a look at a very interesting tool ...
