Magnetic Control of Proteins: More than a Dream

Mike Lacy September 24, 2024

Lots of scientists work to invent novel techniques or to engineer improved tools for familiar applications. But how does one invent a tool for applications that don’t even exist yet? Andrew York, Maria Ingaramo, and their team at Calico Life Sciences recently set out to do just ...
Two graphs, of fluorescence versus time and the residual (F - F_fit)/F_fit versus time, with vertical bands alternating gray and white every 5 seconds. The signal follows a prominent sawtooth pattern, decreasing during the gray period and recovering during the white period. Bottom panel (residuals) indicates ΔF/F reaches 75% and decreases slightly each cycle, but still reaches over 50% after seven cycles.

Live and Let Dye: Self-Labeling Protein Tags

Mike Lacy April 16, 2024

If you take a look in a typical lab freezer, you’ll probably find lots of different plasmids containing the same protein of interest tagged with different fusion proteins for different experiments over the years — a green fluorescent protein, a red fluorescent protein, a fancy ...

New Optogenetic Tools for Cytoskeleton and Membrane Control

Mike Lacy September 28, 2023

Optogenetics gives you the power to control cells or organisms with the flip of a switch. You may be familiar with popular light-sensitive ion channels used to control activities like neuronal signaling — think of a mouse with an LED brain implant or a worm wiggling back and ...

Antibodies 101: Multiplex Immunofluorescence

Mike Lacy May 23, 2023

You may be familiar with immunofluorescence (IF, often referred to as immunocytochemistry (ICC) when the sample is cultured cells or immunohistochemistry (IHC) with tissues), where an antibody binds a target protein in your sample, then a fluorescently labeled secondary antibody ...

Hot Biosensors 2022: Year-End Roundup

Mike Lacy December 6, 2022

Here at Addgene’s headquarters, the skies are getting dark and wintry with the end of year approaching. We’re always looking for something to brighten our day, whether it’s memories of summer or just a bright new plasmid. One area with lots of bright new plasmids is our ...

Summer SciComm: Preprints

Mike Lacy August 16, 2022

As a scientist, perhaps the most important part of your research is communicating the results of the work. Yes, those control experiments are important - but without letting other scientists know the results, your work won’t have any impact!

Split Fluorescent Proteins for Studying Protein-Protein Interactions

Mike Lacy May 3, 2022

Many, many techniques are available to assess protein-protein interactions. One popular approach is to fuse a protein of interest to each part of a split fluorescent protein (FP) and measure the signal produced when the candidate proteins’ interaction brings the pieces of the FP ...
