P846 – LDA (Low Diffusable contrast Agent)

470.00 

Category: Preclinical MRI probes

Description

Catalogue Number P846
Description 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
Main Applications Contrast-Enhanced MR angiography, tissue perfusion, angiogenesis imaging (DCE, MRI, Ktrans analysis, blood volume imaging, permeability measurement, treatment follow-up)
Molecular characteristics

–  Gd content: one Gd atom per molecule

–  Hydrodynamic size: diameter is 2-3 nm

–  Molecular weight: 3.5 kDa

–  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.

 

Characteristics of the vial –  Concentration: [Gd] = 20 mmol/L
