Study of platelet membrane proteins through fluorescence polarization of diphenyl hexatriene
Abstract:
Fluorescence polarization (FP) of diphenylhexatriene (DPH) has been currently interpreted as cell membrane fluidity. We studied here FP of DPH labelled platelets under activation of membrane enzymes and concluded that FP of DPH could rather reveal interactions with hydrophobic pockets of membrane proteins.
