Description

General description

5-Carboxyfluorescein, also known as 5-FAM, is a green fluorescent product. It is derived from cleavage of 5-Carboxyfluorescein diacetate by intracellular esterases. In viable cells, the fluorescent molecule is impermeable to the cellular membrane.

Application

5-Carboxyfluorescein has been used as a payload to study leakage phenomena on sesame (Sesamum indicum L.) and coconut (Cocos nucifera L.) liposomes.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Derivative of fluorescein giving stable derivative upon conjugation with biopolymers[1][2]
