Liposome Encapsulation Services: Antigens

Online Inquiry

BOC Sciences, with its accumulated experience in liposome research, has developed a set of methods using liposomes as antigen carriers to prepare anti-low immunogenic vaccines.

For some molecules with very weak auto-immunogenicity, subdivision, glycolipids, multiples, DNA, etc., it is often difficult to achieve high specificity for the target antigen even using carrier interconnection methods to increase their immunogenicity. Liposomes have been regarded as a new type of adjuvant or vaccine implantation carrier due to their excellent antigen-stimulating activity.

Key Advantages of Liposome Vaccines

Safety and tolerability

Low-reactivity

Since liposomes usually consist of lipids naturally present in cell membranes, such as PC and cholesterol, these formulations are fully biodegradable

Versatility

Lipid components and vesicle preparation methods can be adjusted to achieve desired physicochemical properties for liposome formulations. Hydrophilic molecules can be encapsulated within the aqueous interior or bound to the surface of the vesicles, while hydrophobic compounds can be inserted into the lipid bilayer. This versatility allows the incorporation of all types of antigens, including peptides, proteins, carbohydrates, nucleic acids, and small molecules, into liposomal formulations, and the vesicle properties are modified to accommodate the size and charge of the antigen.
