| Study ID | ST002724 |
| Study Title | Ceramides profile in HeLa overexpressing nSMase2 (SMPD3) |
| Study Type | Lipidomics LC-MS/MS |
| Study Summary | This study aim to determine which species of ceramides are modified by overexpression of the protein neutral sphingomyelinase 2 (nSMase2, gene SMPD3). HeLa cells were transfected with a plasmid containing V5-tagged nSMase2. Lipids were extracted after 24h after transfection and the sphingolipid profile was determined by LC-MS/MS. |
