Intermediate molecular weighted compound, constituted by a macrocyclic gadolinium chelate. Blood pharmacokinetic very comparable to that of Gd-DOTA or Gd-DTPA but limited extravasation within the capillary bed
– Dose: due to high relaxivity of P846, the injected dose is lower than that of conventional contrast agent like Gd-DOTA
Recommended dose: 50 μmol/kg = 2.5 μL/g
Example: for a 30g body weight mouse, injection volume is 75 μL
– Relaxivities (s-1.mM-1, 37°C, Human Albumin Serum 4%)

– In vitro quantification techniques: P846 is a Gd-based contrast agent. Gd can be dosed by ICP-AES or ICP-MS. Another way to quantify Gd chelates is by T1 or T2 relaxometry, with assumption of r1 or r2.
