AlhydroVet is an aluminium hydroxide gel product specifically manufactured for use as an adjuvant in veterinary vaccines. The gel is a suspension of boehmite-like (aluminium oxyhydroxide) hydrated nano/micron size crystals in loose aggregates. The product has very low conductivity due to the absence of buffering ions. It has a positive charge at neutral pH and effectively adsorbs negatively charged antigens. The product is available as AlhydroVet 2%, containing approximately 10mg/ml aluminium.
