Molecular Weight
PEG 1 kDa
Source
Chemical synthesis
Solubility
PEI-PEG-lactosyl 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
PEI conjugated to lactosyl with a 1 kDa PEG spacer can be used to examine the influence of PEGylation on the cytotoxicity and non-specific interactions of carbohydrate-modified PEI.
