Properties
Description
This research tool provides a highly pure (≥95%) DTPA derivative of lactosyl, connected by a 5 kDa polyethylene glycol (PEG) chain for research on carbohydrate-targeted metal delivery systems.
Molecular Weight
PEG 5 kDa
Source
Chemical synthesis
Solubility
Lactosyl-PEG-DTPA is soluble in a wide range of organic solvents, such as DCM, DMF, and DMSO, and shows excellent solubility in water.
Identity
Confirmed by NMR.
Applications
Lactosyl-PEG-DTPA with a 5 kDa PEG spacer can be employed to study the impact of steric hindrance from the PEG chain on the binding affinity of the carbohydrate ligand to its target receptor using MRI-based assays.
