PRISTANE(Cas 1921-70-6) Usage

Biochem/physiol Actions

Pristane is a hydrocarbon oil adjuvant widely used to induce tumorigenesis in mice and arthritis and lupus nephritis in rats. It works as a adjuvant for monoclonal antibody generation in mouse ascites.

Purification Methods

Purify pristane by shaking it with conc H2SO4 (care, if amount of pristane is too small then it should be diluted with pet ether not Et2O which is quite soluble H2SO4), then H2O (care, as it may heat up in contact with conc H2SO4), dry (MgSO4), evaporate and distil it over Na. [S.rensen & S.rensen Acta Chem Scand 3 939 1949, Beilstein 1 III 570.]

Definition

ChEBI: A norterpene that is an acyclic saturated hydrocarbon derived from phytane by loss of its C-16 terminal methyl group.

General Description

Pristane is a natural saturated terpenoid alkane used in research on the pathogenesis of autoimmune diseases such as arthritis and lupus.
