Description

Packaging

1 kg in poly bottle

25, 100, 500 g in poly bottle

Preparation Note

Blended from various seaweeds to produce rigid gels.

Application

Carrageenans are used to suppress immune response in vivo and in vitro via mechanisms believed to involve selective cytopathic effect on macrophages. As ι-, κ-, and λ-carrageenans have varying degress of sulfation, they may be studied comparatively for differences in protective, antiviral, and immunosuppression activities.

As ι-, κ-, and λ- carrageenans have varying degrees of sulfation, they may be studied comparatively for differences in protective, antiviral, and immunosuppression activities. Carrageenan may be used in the development of biomaterials such as bone graft substitutes; entrapping vessels such as biobeads and encapsulation vehicles for drug delivery. Carrageenan be used to develop hydrogels.

General description

Carrageenans are mucopolysaccharides from the cell walls of the red algae. They are anionic linear polymers composed of 1,3α-1,4β-galactans having one (κ-), two (ι-) or three (λ-) sulfates per disaccharide unit. In ionic solutions, κ- and ι-carrageenans self-associate into helical structures that form rigid or flexible gels, respectively. λ-carrageenans do not form helices and are non-gelling. Carrageenans are used commercially as thickeners and stabilizing agents.
