TMA-DPH (solution)

TMA-DPH (solution) is a hydrophobic fluorescent membrane probe (Ex=355 nm; Em=430 nm) . TMA-DPH is able to anchor on the cell surface and localize to different regions of the phospholipid bilayer. By analyzing the fluorescence polarization values of TMA-DPH in the plasma membrane and membrane substructures, the fluidity of the cell membrane can be determined[1][2][3].Solvent and concentration: DMSO: 10 mM
