Phospholipids are phosphoric acid esters of fatty acid, which are major components of all cell membranes. It is well known that the thin polar membrane is made of two phospholipid layers (lipid bilayers) due to the amphiphilic property. As an example of lipid bilayer, liposomes have capsule structure which can contain small amounts of other molecules. Liposomes consisting of phospholipids such as
DMPC (Product No.
D3924),
DSPE (Product No.
D4214) and
DOPG Sodium Salt (Product No.
D5318) can be applied to controlled release dosage, drug delivery systems, and cosmetics.
1) PEG-modified phospholipids such as
Methly-PEG2000-DSPE (Product No.
M3264) have been developed to improve the retention of liposomes in blood,
2) and charge-reversible phospholipids such as
DOP-DEDA (Product No.
D6219) have enabled nucleic acid delivery via liposomes.
3) We also offer
high-purity cholesterol (>99%) (Product No.
C3624) which is used in the preparation of liposomes.
