Alhydrogel® adjuvant 2%
Vaccine Adjuvant: Aluminium hydroxide gel
Alhydrogel® adjuvant 2%, referred to as alum, is an aluminium hydroxide wet gel suspension. Alum induces a Th2 response by improving the attraction and uptake of antigen by antigen-presenting cells (APCs). It can also activate innate immunity pathways triggered by pattern recognition receptors (PRRs).
Alhydrogel® adjuvant is sterilized by autoclavation and aseptically filled.

Alhydrogel adjuvant 2% is an aluminium hydroxide (referred to as alum) wet gel suspension. Alum acts primarily through the formation of a depot at the injection site, enabling enhanced antigen availability, activation of antigen presenting cells (APCs) and uptake by immune cells . It can also activate innate immunity pathways triggered by pattern recognition receptors (PRRs). The NLR pathway has been recently described as an important mechanism in alum adjuvancy . Alum has been shown to activate the NLRP3 inflammasome although its role in alum-induced antibody response is controversial .
