C-12 NBD Ceramide
Cayman Chemical Item Number 10007958
Description
Ceramidase catalyzes the hydrolysis of the N-acyl linkage between the fatty acid and sphingosine base in ceramide to produce sphingosine and a free fatty acid. Three isoforms of ceramidases (acid, neutral, and alkaline) have been characterized based on differences in their catalytic pH optimum.1↗,2↗ C-12 NBD ceramide is a long-chain fluorescent ceramide analog that can be used for the measurement of alkaline and neutral ceramidase activity.3↗ It is hydrolyzed efficiently by alkaline ceramidase from P. aeruginosa and by neutral ceramidase from mouse liver. In addition, alkaline and neutral ceramidases from a variety of mammalian cell lines also hydrolyze C-12 NBD ceramide. Acid ceramidase does not appear to utilize C-12 NBD ceramide as a substrate. The possibility exists for C-12 NBD ceramide to also be applied to the measurement of ceramide kinase and/or sphingomyelin synthase activity.
