Figure 1: The fluorescent protein color palette has expanded ∼140 nm into longer wavelengths over the past 15 years to include many new variants in the orange, red and far-red spectral regions.

Today, both natural and engineered fluorescent proteins come in a veritable rainbow of colors, largely thanks to pioneering work done in Roger Tsien's laboratory at the University of California at ...

While bioluminescent proteins offer several advantages over fluorescent proteins, the limited availability of color variants has made it difficult to observe multiple targets simultaneously.

Many fluorescent proteins can be purchased online through Addgene. A wide array of synthetic fluorescent probes can be purchased online through Molecular Probes.

Cats come in all sorts of colors—tabby, orange, and calico—but scientists are most interested ... Poeschla and colleagues used a modified virus to transfer the green fluorescent protein gene into cat ...

PF555 offers significantly greater photostability than existing fluorescent dyes, making it highly effective for tracking both individual proteins at the single-molecule level and multiple ...
