New Preprint: High-intensity 365 nm irradiation accelerates photoreactions in living cells by up to 1000×. We show protein–drug 💊, –protein 💪, –DNA 🧬, –RNA 🧬 crosslinking within seconds, and analysis by #massspec for #proteomics, #chembio, #chromatin and #RNAbiology. www.biorxiv.org/content/10.1...
