c-12 galactosylceramide (d18:1/12:0)

C12 Galactosylceramide is a bioactive sphingolipid. It inhibits IL-4 production by 53.84% in EL4 T cells when used at a concentration of 10 μM. C12 Galactosylceramide reduces the growth of human papillomavirus type 16-associated tumors in mice and reduces tumor recurrence following surgical removal or chemotherapy. It also reduces natural killer T cell activity, delays the onset of proteinuria, and improves survival in a mouse model of systemic lupus.

C12-Ceramide (C12 Ceramide (d18:1/12:0)), a ceramide present in the protective membranes surrounding umbilical cord blood vessels in infants born to women with pre-eclampsia, can be used to assess the level of ASM activity in the plasma of patients with Niemann-Pick disease.

BODIPY-C12 Ceramide (B12Cer) is a fluorescently-tagged form of C12 ceramide, with excitation/emission maxima at 505/540 nm, respectively. It is a fluorescently-labeled sphingolipid and has been utilized for quantifying acid sphingomyelinase activity in the plasma of patients with Niemann-Pick disease.
