DPPE-PEG5000
Based on 1 Customer Validation
DPPE-PEG5000 (16:0 PEG5000 PE) is a polymer-lipid conjugate and LipoParticle stabilizer with a PEG chain of 5,000 g/mol molecular weight attached to its polar head, and it can be internalized by biological membranes. DPPE-PEG5000 enables LipoParticle to maintain colloidal stability after 20-fold dilution in PBS or cell culture medium, and prevents aggregate formation during lyophilization and rehydration. DPPE-PEG5000 helps enhance the non-cytotoxic property of LipoParticle formulations against human osteoblasts. DPPE-PEG5000 serves as a PEG lipid functional end group for synthesizing liposomes (LPs), is used in the design of conjugated polymer nanoparticles, and applies to research related to bone and joint infections.

Biological Activity
DPPE-PEG5000 (2 mol./mol. total lipid) imparts colloidal stability to LipoParticles upon 20-fold dilution in PBS or cell culture medium and enables freeze-drying and rehydration without significant aggregation, while maintaining defined size, size distribution, and surface charge profiles[1].
DPPE-PEG5000 (2 mol./mol. total lipid; 19.5-1250 μg/mL LipoParticles; 24 h) forms LipoParticles that are non-cytotoxic to human osteoblast MG63 cells at concentrations up to 1250 μg/mL after 24 h of incubation, with no reduction in cell metabolic activity[1].
DPPE-PEG5000 (2 mol./mol. total lipid; 3,000 colloids per cell; 24 h) forms LipoParticles that are efficiently internalized into human osteoblast MG63 cells after 24 h of incubation at a dose of 3,000 colloids per cell, with localization in the cellular cytoplasm[1].
DPPE-PEG5000 (2 mol./mol. total lipid; 22,000 colloids per cell; 24 h) forms LipoParticles that are internalized into human osteoblast MG63 cells after 24 h of incubation at a dose of 22,000 colloids per cell, with measurable fluorescence signals from both the PLGA core and lipid coating, and maintain high cell viability (89.7%)[1].
DPPE-PEG5000 (2 mol./mol. total lipid; 22,000 colloids per infected cell; 24 h) forms LipoParticles that are internalized into Staphylococcus aureus-infected human osteoblast MG63 cells after 24 h of incubation at a dose of 22,000 colloids per cell, with localization near intracellular bacteria[1].
