Who doesn't love a library? A pooled library, that is! Grab a hot drink and your reading glasses and enjoy browsing the libraries Addgene has to offer:
https://twp.ai/4it3AO
A venn diagram comparing Libraries and Pooled Libraries. The Libraries circle reads "made of paper" and shows an illustration of books. The Pooled Libraries circle reads "made of DNA (and sometimes lentivirus)" and shows an illustration of plasmids. In the overlap of the two circles, three entries read: "incredible community driven resource; source of new discoveries; barcodes."

Looking for tools to control gene expression or build new models? Explore Addgene’s collection of Cre-lox and other site-specific recombinases (Flp, Dre, and more) to find the right system for your research. https://twp.ai/4ir8li
Three-panel illustration depicting recombination outcomes using Cre-lox as an example. A DNA strand is shown as a horizontal line with Gene X as an arrow, flanked by triangle target sites in opposite directions (panel A) or in the same direction (panel B). In panel C, two parallel DNA strands are shown with one target site on each strand in the same direction. In each panel, scissors represent Cre recombinase with an arrow pointing to the resulting rearrangement.

On-again, off-again with your favorite gene? Maybe some new plasmids are just what your experiment needs! Check out our recently updated Tetracycline Inducible Expression collection page!
🧬: https://twp.ai/4is3BR
A series of schematics, each with one illustration of the system without tetracycline (or dox) and one with tetracycline present. Left (TetR): without tetracycline, the TetR protein binds to DNA at the tetO site and transcription of the downstream gene is blocked; with tetracycline bound, TetR releases from the DNA and transcription occurs. Center (Tet-Off): without tetracycline, the tTA binds to DNA at the TRE and enhances transcription of the downstream gene; with tetracycline bound, tTA releases from the TRE and transcription halts. Right (Tet-On): without tetracycline, the rtTA does not bind to the TRE and transcription halts; with tetracycline bound, rtTA binds the TRE and enhances transcription of the downstream gene.
