AMSTERDAM, April 13, 2023 — The University of Amsterdam research team that introduced the red fluorescent protein known as mScarlet in 2016 has introduced an improved variant of the marker. A version of mScarlet called mScarlet3 delivers a quantum yield of 75% and a fluorescence lifetime of 4.0 ns. In addition to providing what the researchers said is record-level brightness, mScarlet3 provides fast, complete maturation. Fluorescent proteins like mScarlet3 are attached to cells to help scientists observe the
