Properties
Description
The 2 kDa DPPE-modified chitosan-PEG material (98% pure) should be preserved in lyophilized form, limiting dissolution steps to safeguard functional performance.
Targets
DSPE-PEG-chitosan is a chitosan derivative with a molecular weight of 2 kDa and a purity of 98%. It features functional group of DSPE. When handling this material, it is essential to maintain its dry state and minimize frequent dissolving and lyophilization processes to preserve its integrity and efficacy.
