Medical Definition of Resorcinol phthalic anhydride
1.
Fluorophore commonly used in microscopy.
Fluorescein di acetate can be used as a vital stain or can be conjugated to proteins (particularly antibodies) using isothiocyanate.
Excitation is at 365nm and the emitted light is green yellow (450-490nm). The emission spectrum is pH sensitive and fluorescein can therefore be used to measure pH in intracellular compartments.
