Molecular cloning requires some method of screening colonies for the presence of an insert. Traditionally this has been done with restriction enzyme digest; however colony PCR can accomplish the same thing in less time and for less money. The key steps to colony PCR are: 1) ...
Over 25 million people worldwide are currently infected with the lentivirus HIV-1. Today, HIV-1 can be controlled with antiviral therapies such that the virus is undetectable in the blood. But the virus doesn’t completely disappear; it just hides in latently infected cells. To ...
This post was contributed by ATCC Outreach Scientist Nick Amiss. Cell culture in the present day Cell culture is a widespread tool used in the fields of oncology, virology, immunology, microbiology, and pharmacology (many of which are represented in Addgene's Special ...
The crisis of antibiotic resistance is upon us, and the world is unprepared. Each year in the United States, two million people will be infected by antibiotic resistant bacteria. Even when researchers develop new antibiotics, the onset of resistance is swift, as few as five ...
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 ...
This post was contributed by guest blogger Erik L. Snapp. Stop using EGFP/GFP for fusion proteins! Despite multiple studies in high profile journal articles, many researchers remain unaware that EGFP/GFP is prone to forming noncovalent dimers. This property of EGFP can lead to ...
This post was contributed by guest blogger Jessica Polka, a Postdoctoral Research Fellow with Pamela Silver. Most types of biological motion (whether endocytosis, vesicle trafficking, or muscle contractions) are produced by orchestrated movements of networks of proteins ...
