Adjuvant Platform Technology

Adjuvant Platform Technology?

  • Adjuvant is a substance used in combination with an antigen to enhance the in vivo cellular and humoral immune response to a particular antigen.
  • Alum, which was developed over 70 years ago, is the most widely used immune enhancer used in commercial vaccines.
  • In recent years, many researches have been achieved on innate immunity, and an innate immunity enhancer is being used as an adjuvant.
  • Thus, the adjuvant can be used as a vaccine for various diseases by replacing only specific antigens, and we are working on applying them to various fields.
