Biological Activity

[Description]:

Pristane (Norphytane) is a naturally occurring hydrocarbon oil found in small quantities in many plants, in various marine organisms, and as the most active component of mineral oil[1]. Pristane is a non-antigenic adjuvant, and induces MHC class II-restricted, arthritogenic T cells in the rat[2].

Research Areas >> Inflammation/Immunology

[In Vitro]

Pristane activates CD4+ αβT cells that are MHC class II restricted and arthritogenic[1].

[In Vivo]

Pristane activates CD4+ alpha beta T cells that are MHC class II restricted and arthritogenic in vivo[2]. Animal Model: Naive recipient rats (DA)[2] Dosage: 500 μL of Pristane oil Administration: Intradermal injection Result: Both CD4+, CD8+ αβT cells and B cells significantly expand in draining lymph nodes until day 6 after injection, whereafter the CD4+ αβT cells continue to expand until day 12 after injection.
