 The diffusion coefficient of ATTO488 carboxilic acid has been measured to be 400 µm²/s at 25°C. Published diffusion coefficients of various fluorophores are summarized in the Technical Note "Absolute Diffusion Coefficients: Compilation of Reference Data for FCS Calibration" available from PicoQuant [see [[http://www.picoquant.com/images/uploads/page/files/7353/appnote_diffusioncoefficients.pdf]]]. This list is extensive, but does not claim to be complete.\\ The diffusion coefficient of ATTO488 carboxilic acid has been measured to be 400 µm²/s at 25°C.
