A biologically active, cell-permeable, but nonphysiologic ceramide analog. It activates protein phosphatase 2A and MAP kinase (MAPK/ERK), suppresses insulin-induced tyrosine phosphorylation and inhibits glycoprotein traffic by the secretory pathway. It inhibits diacylglycerol accumulation and phospholipase D activation in fibroblasts. It induces an arrest at the G0/G1 transition of the cell cycle (10μM) and causes apoptosis (15μM or greater) in Molt-4 leukemia cells. Alternative name: N-Hexanoyl-D-erythro-sphingosine. Purity: ≥98% (TLC). Solubility: Soluble in 100% ethanol (>25mg/ml) and DMSO (>50mg/ml). Long Term Storage: -20°C.
