Alhydrogel® 2%

Vaccine Adjuvant: Aluminium hydroxide gel

Alhydrogel® 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® is sterilized by autoclavation and aseptically filled. InvivoGen only sells products for research use
Alhydrogel® is a trademark of Brenntag Biosector.

Alhydrogel® production line has been under investigation by Brenntag Biosector to ensure product specifications. Internal investigation is currently being finalised. 
Production, release and distribution of Alhydrogel® will resume in December.

Description

Alhydrogel 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].
