Cellsome®-Natural saturated PC extract catalog is composed of four liposomes made from phosphatidylcholine (PC) lipids. These lipids are from natural lipids that are extracted from either egg yolk or soybean. The unsaturated natural extracted lipids go through hydrogenation process and fully saturated lipids are made and the liposomes are formulated from these hydrogenated lipids with and without cholesterol. Adding 30% cholesterol makes the liposomes serum stable and is necessary when the liposomes are used in the presence of serum.

Hydrogenated soy PC is composed of mainly two saturated lipids:  88.6% of 18:0 lipid and 11.4% of 16:0 lipid.

Hydrogenated egg PC is composed of mainly five saturated lipids: 0.1% of 14:0 lipid, 32.2% of 16:0 lipid, 60.6% of 18:0 lipid, 4.5% of 20:0 lipid, and 2.2% of 22:0 lipid.

Lyophosome™ product catalog is composed of a large selection of freeze-dried liposomes with various types of lipids and wide range of zeta potentials and different properties. Lyophosome™ products should be used by scientists who understand liposome formulation and have the proper equipment to check the size, separate non-encapsulated drugs and do the proper assays. Freeze-dried liposomes cannot be used blindly.
