Oil-based Delivery Systems Development Services

Oil-based delivery systems do not require the creation of emulsions, simplifying the use of vaccines. Alfa Cytology provides high-quality oil-based delivery system development services to help our clients with cancer vaccine development.

Introduction to Oil-based Delivery Systems

Oil emulsions are often used as a vaccine delivery platform, facilitating the slow release of antigens by forming a reservoir at the injection site. The antigens are trapped in the water phase and are passively released as the emulsion degrades in the body. However, oil-based delivery systems simplify vaccine administration by eliminating the need for emulsion formation.

Oil-based delivery systems can suspend vaccine components directly in the oil thinner, forcing immune cells to actively absorb formulation components without passive release. It can be custom-formulated using a mixture of CD8+ T-cell peptide epitopes, T-helper epitopes, and adjuvants of choice. Liposomes carry hydrophilic antigens and adjuvants directly into the oil medium, capturing all vaccine components in a form suitable for efficient uptake and processing/presentation by antigen-presenting cells (APCs).

Our Service

Oil-based delivery systems in cancer vaccines are a special type of vaccine formulation that has been developed to improve the effectiveness of cancer vaccines by enhancing antigen presentation, promoting immune cell activation, and prolonging the immune response. Targeting different customer needs, Alfa Cytology provides comprehensive oil-based delivery systems development services, including but not limited to the following.

Water-free oil-based formulation, no need to form an emulsion, as the formulation does not contain water-based ingredients. When used with cancer antigens, a strong and long-lasting T-cell immune response can be generated. Adjuvants can also be included to help initiate and direct the immune response. The antigens and adjuvants were prepared in liposomes and then lyophilized. The resulting cake is reconstructed directly in the oil before use. The presence of lipids ensures that all ingredients in the formula are suspended in the oil. Vaccine-induced antigen-specific T cells can be detected in the circulatory system and tumor microenvironment. When used in combination with other forms of immunotherapy, the induced active immune response can be further enhanced.

Methods of coating proteins with surfactants have made enough progress to successfully establish oil-in-solid (S/O) dispersion techniques. Oil-based dispersions containing proteins have the potential for a variety of applications. In particular, the low efficiency of macromolecule absorption can be overcome by oral administration as well as skin administration, and the convenience of administration is user-friendly. In addition, compared with S/O delivery systems containing only tumor-associated antigen (TAA), co-delivery with immunomodulators significantly enhanced the anti-tumor immune response, thereby inhibiting tumor growth and extending survival time in mice.
