StorageShould always be stored in a freezer at at -40 °C or -80 °C. Upon adding water to proliposomes, liposomes are formed.
AppearanceWhite lyophilized powder. Liposomes are formed upon adding water to the freeze dried proliposomes and the appearance of the formulation will be white translucent liquid.
DescriptionLiposomes are extensively used to study the interaction of proteins, peptides and other molecules with the surface of a lipid membrane. One of the parameters that affects this interaction is the charge of the liposomal membrane. Liposomes are always made in aqueous environment and they are sized to the desired size in liquid state using various methods such as high pressure extrusion through nano sized pore track etch membranes. Liposome without water is meaningless. In rare occasions, liposomes are freeze dried and proliposomes are formed in the presence of a lyoprotectant such as trehalose. Using a lyoprotectant is necessary in order to maintain the size of the liposomes after rehydration. Phosphatidylserine (PS) is a negatively charged molecule. The amount of the negative zeta potential in the liposomes depends on the molar percentage of the phosphatidylserine (PS) in the formulation. Phosphatidylserine (PS)-based Liposomes contain products made from 0.5 up to 90 percent DOPS with various amount of negative zeta potentials. The matrix lipid, DOPC, that is used in the formulations does not significantly contribute to the charge of the liposomes. Anionic liposomes are used in blood complement studies and various types of in vitro studies.

BufferLyophilized Phosphate Buffered Saline, 7.4 (after hydration)
Shelf-life6 months.
Technical NotesLiposomes are formed upon hydration of the lyophilized formulation. If the lyophilized liposomes are hydrated with solution containing a water soluble drug then a large percentage of the drug will stay outside of the liposomes and in non-encapsulated form. It is advised to use a micro dialysis cassette or a spin column using the right side beads (depending on the size of your drug) and separate the drug encapsulated liposomes from free drug and perform the drug assay in order to calculate the encapsulation efficiency. Lyophilized liposomes are mainly recommended to be used with drugs that have a short life in aqueous solution mainly due to hydrolysis. After adding the solution of the drug to lyophilized liposomes, the liposomes should be used immediately. Lyophilized Liposomes products should be used by scientists who understand liposome formulation and have the proper equipment in order to check the size, separate the non-encapsulated drug and do the proper assays. Trehalose is used as a lyoprotectant in all freeze dried liposome formulation. The size distribution after hydration of the freeze dried formulation will be around 100 nm.
