Kodi Fluorescein Sodium CAS 518-47-8 ndi chiyani?

Fluorescein Sodium ndi yopanda fungo komanso hygroscopic. Kusungunuka m'madzi, yankho limawoneka lachikasu lofiira ndi lamphamvu lachikasu lobiriwira la fluorescence, limasowa pambuyo pa acidification, limawonekeranso pambuyo pa neutralization kapena alkalization, sungunuka pang'ono mu Mowa, pafupifupi wosasungunuka mu chloroform ndi ether. Njira yothetsera madzi ndi isotonic ndi plasma.

Kugwiritsa ntchito

Fluorescein Sodium amagwiritsidwa ntchito ngati fulorosenti tracer kuphunzira permeability wa magazi-ubongo chotchinga (BBB) ndi magazi-ubongo chotchinga (BSCB) mu zitsanzo makoswe. Pogwiritsa ntchito utoto uwu ngati gawo laling'ono, kayendedwe kamankhwala kachiwindi kolumikizidwa ndi organic anion transport peptide (OATP) idaphunziridwa.
