General description

Stable solution in PBS. Miscible and stable in common buffers, serum and blood. Store in dark at 4°C. Suitable excitation wavelengths: 785 nm, 808 nm. Emission: 900-1400 nm, peak ~ 1050 nm. Quantum yield (QY) ~2% based on 0.5% QY of IR26 in 1,2 dichloroethane under 808 nm excitation. Quantum yield is ~4X of common Hipco single walled carbon nanotubes. For in vivo imaging (e.g., vessels), inject ~100-150 µg in ~200 µL solution for a typical nude mouse but the dose can be varied. Circulation half time of the dye is about 1 hour.
