Docosahexaenoic acid-d5 (DHA-d5) is intended for use as an internal standard for the quantification of DHA (Cay-90310) by GC- or LC-MS. DHA is a long-chain omega-3 polyunsaturated fatty acid (PUFA) found in fish and algal oils. It comprises approximately 40% of total brain PUFAs and is abundant in grey matter and...

Eicosapentaenoic acid-d5 (EPA-d5) is intended for use as an internal standard for the quantification of EPA (Cay-90110, Cay-90110.1, Cay-26415) by GC- or LC-MS. EPA is an omega-3 fatty acid abundantly available in marine organisms. It is oxygenated by COX-1 and COX-2 at rates of about 5% and 30%, respectively,...

Stearidonic Acid (18:4omega-3) is a rare polyunsaturated fatty acid of the omega-3 series. In normal humans, it represents less than 0.25% of serum phospholipid fatty acids. It is present in certain natural oils such as echium and black currant seed, and to the extent that these oils are incorporated into...

Phosphatase and tensin homolog (PTEN) is a tumor suppressor with roles in cell division, cell migration, and apoptosis. It is ubiquitously expressed and localized to the cytosol and nucleus where it dephosphorylates phosphatidylinositol-(3,4,5)-triphosphate (PIP3) to phosphatidylinositol-(3,4)-diphosphate (PIP2) to...
