NH2-PEG-DMG, 2K
Price range: $302.00 through $756.00
NH₂-PEG-DMG, 2K is primarily used for constructing lipid nanoparticles (LNPs) and nucleic acid delivery systems by leveraging the DMG (dimyristoyl glycerol) moiety for membrane integration and the terminal amine for covalent conjugation to therapeutic payloads or targeting ligands. Its key benefits include enhanced stability, biocompatibility, and efficient cellular uptake due to the PEG spacer’s stealth properties and the amine group’s versatility in bioconjugation.
DSPE-PEG2K-CH2CH2COOH
DSPE-PEG₂₋CH₂CH₂COOH, 2K is primarily used for constructing functionalized liposomes and lipid nanoparticles (LNPs) by conjugating amine-bearing ligands via EDC/sulfo-NHS chemistry, enabling targeted drug delivery and biomedical imaging. Its key benefits include enhanced colloidal stability, reduced immunogenicity, and versatile ligand attachment due to the PEG spacer’s stealth properties and the terminal carboxyl group for covalent modification.
DSPE-PEG-NHS, 2K
Price range: $155.00 through $233.00
DSPE-PEG₂₋CH₂CH₂COONHS, 2K is primarily used for constructing functionalized liposomes and lipid nanoparticles (LNPs) by conjugating amine-bearing ligands (e.g., antibodies, peptides) to the terminal NHS ester, enabling targeted drug delivery and diagnostic imaging. Its key benefits include enhanced stability, biocompatibility, and precise targeting capability due to the PEG spacer’s stealth properties and the reactive NHS ester for efficient covalent coupling.
DSG-PEG-NH2, 2K
Price range: $155.00 through $728.00
DSG-PEG₂₋NH₂, 2K is primarily used as a heterobifunctional crosslinker for conjugating amines (via its DSG moiety) to other functional groups (via its terminal amine), enabling applications in protein-protein crosslinking, surface immobilization, and biomolecule detection. Its key benefits include enhanced water solubility, reduced steric hindrance from the PEG spacer, and dual reactivity for flexible bioconjugation strategies, though it requires pH control (optimal pH 7.0–7.4) to maintain efficiency.
mPEG-DAG,2K
mPEG-DAG, 2K is primarily used for constructing cell-penetrating or membrane-anchored drug delivery systems, leveraging the diacylglycerol (DAG) moiety for lipid membrane integration. Its key benefits include enhanced cellular uptake, biocompatibility, and versatile targeting capabilities due to the PEG spacer's stealth properties and heterobifunctional design.
