Novel two-photon (TP) probes were developed for lysosomes (PLT-yellow) and mitochondria (BMT-blue and PMT-yellow). These probes emitted strong TP-excited fluorescence in cells at widely separated wavelength regions and displayed high organelle selectivity, good cell permeability, low cytotoxicity, and pH insensitivity. The BMT-blue and PLT-yellow probes(More)
We have developed a two-photon fluorescent tracer (Pyr-affibody) that shows high selectivity for human epidermal growth factor receptor-2 (HER-2). Pyr-affibody showed absorption and emission maxima at 439 and 574 nm, respectively, with a two-photon absorption cross-section value of 40 × 10(-50) cm(4)s/photon (GM) at 750 nm in aqueous buffer solution.
