Aluminium Phosphate Gel primarily functions by forming stable complexes through the adsorption of antigens, thereby delaying antigen release and enhancing immune responses. Its high specific surface area and surface charge facilitate antigen recognition by antigen-presenting cells (APCs), effectively activating B-cell and T-cell responses. This leads to improved antibody titers and enhanced immune memory effects. Additionally, Aluminium Phosphate Gel exhibits low toxicity, excellent biocompatibility, and remarkable stability, making it a suitable adjuvant for various applications.
