Description

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.
