Monomeric near-infrared (NIR) fluorescent proteins (FPs) from bacterial phytochromes bring potential advantages, but their brightness in cells is lower than dimeric NIR FPs. Here the authors develop enhanced monomeric NIR FPs enabling imaging across different scales without the trade-off between brightness and monomeric state.
