Biological Activity

Near-infrared probe that binds to Aβ40 aggregates (Kd = 38 nM) and elicits an emission blue shift. Shown to bind to plaques in APP-PS1 transgenic mice, in vitro. Detects senile plaques in 19-month-old Tg2576 mice in vivo. Penetrates the blood-brain barrier.

Preparing Stock Solutions

The following data is based on the product molecular weight 410.26. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.44 mL 12.19 mL 24.37 mL
5 mM 0.49 mL 2.44 mL 4.87 mL
10 mM 0.24 mL 1.22 mL 2.44 mL
50 mM 0.05 mL 0.24 mL 0.49 mL
