This is a really, really important story, which is why I provided a gift link. Many people, when they think of higher education, think of elite universities. But most higher education is nonselective (i.e., they admit everyone), and a lot of it is community colleges.

Happy to see my Postdoc work out @natbiotech.nature.com. Using HaloTag and synthetic fluorophores instead of FPs enables us to shift the spectral properties of kinase activity reporters (KARs) to the far-red 🔬. Huge thanks to everyone involved @jinzhanglab.bsky.social!
