Abstract
Recent progress in fluorescent protein development has generated a large diversity of near-infrared fluorescent proteins, which are rapidly becoming popular probes for a variety of imaging applications. To assist end-users with a selection of the right near-infrared fluorescent protein for a given application, we will conduct a quantitative assessment of intracellular brightness, photostability, and oligomeric state of 19 near-infrared fluorescent proteins in cultured mammalian cells. The top-performing proteins will be further validated for in vivo imaging of neurons in C. elegans, zebrafish, and mice. We will also assess the applicability of the selected NIR FPs for expansion microscopy and two-photon imaging.
