Fluorescent probes for sphingomyelin and cholesterol lipid domains.(2018/02/06 N.N.)
- Lipid rafts are small lipid domains on the cell membrane and are thought to play an important role in signal transduction, endocytosis and more. Because of the lack of appropriate probes to label sphingomyelin and cholesterol individually, detailed analysis of lipid rafts was difficult.
- Dr. Toshihide Kobayashi and his colleagues of the former Lipid Biology Laboratory at RIKEN have developed methods to visualize the lipid rafts using probes of lipid binding proteins fused with fluorescent proteins.
- DNA Bank provides plasmids of the mCherry and GFP fluorescent probes that can label lipid rafts, sphingomyelin and cholesterol. We are looking forward to receiving your request soon.
