Our eminent Principal Oz biosciences has introduced a new product: Lipovax NTA (Ni) Vaccine Adjuvant. LipoVax NTA(Ni) is a liposome-based adjuvant containing phospholipid, cholesterol and nickel-chelating lipid (60:39:1), showing high affinity to bond with electron-rich ligand such as histidine. Therefore, complexes can be generated using Ninitrilotriacetic acid (NTA) and his-tagged proteins or peptides. The resulting liposomes are non-viral biologics delivery systems, self-assembled from metal-chelating lipid and his-tagged immunogens such as envelope glycoproteins. Nickel-based liposome adjuvant is compatible with most immunization procedures: such as intramuscular, intraepidermal, intravenous, intraperitoneal or subcutaneous.
