For laboratory, institutional, and professional use only. Not available for residential or personal purchase. Orders are subject to verification.
Fluorescein sodium salt is a water-soluble xanthene dye supplied as a bright yellow to orange powder. It is widely used as a fluorescent tracer in biological, pharmaceutical, and analytical research applications.
With strong fluorescence characteristics (λex 460 nm / λem 515 nm), fluorescein sodium salt is commonly employed in permeability studies, vascular perfusion research, blood-brain barrier (BBB) transport evaluation, and diagnostic assay development. Its small molecular size and high aqueous solubility make it suitable for tracer and transport studies in both in vitro and in vivo systems.
