ABOUT
Vaccine Adjuvant: Aluminium hydroxide gel
Alhydrogel® adjuvant 2%, referred to as alum, is an aluminum 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).
In contrast to Adju-Phos®, Alhydrogel® particles have a net positive electrical charge at pH 5-7 and thus are well suited for adsorption of negatively charged antigens (e.g. antigens with isoelectric points below the pH of formulation).
Alhydrogel® adjuvant is sterilized by heating and aseptically filled.
Note: Alhydrogel® is a registered trademark that belongs to Croda and is registered in a large number of countries and regions worldwide.
All products are for research use only, and not for human or veterinary use.

Details
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 [1]. 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 [2]. Alum has been shown to activate the NLRP3 inflammasome, although its role in alum-induced antibody response is controversial [3].
