Description

General description

FITC-CM-Dextran, also known as Fluorescein isothiocyanate–Carboxymethyl–Dextran, is an anionic fluorescent probe. The carboxyl group provides the negative charge, which improves the overall permeability of the molecule. It is supplied as a yellow powder that is freely soluble in water and electrolyte solutions. FITC-CM-Dextran is insoluble in most organic samples such as ethanol, methanol, acetone, and chloroform. FITC-CM-Dextran is manufactured by reacting selected dextran fractions with an activated carboxymethyl derivative in alkali, whereby O-carboxymethyl groups are introduced along the dextran chain.

Application

FITC-CM-dextran is used to study drug intake and delivery mechanisms in HeLa cell lines. FITC-CM-Dextran was chosen due to its high water solubility and negative charge. It is also a suitable molecule to be used in encapsulation studies for polymersomal drug delivery systems or Ps DDS. FITC-CM-Dextran is a biocompatible molecule used as a starting material in several pharmaceutical and diagnostic applications.
