Application

FITC-DEAE-Dextran 70 is a cationic fluorescent dextran that may be used to study cell processes such as cell permeability, phagocytosis and endocytosis and to study mechanisms of biomolecular delivery. FITC-DEAE-Dextran 70 may be use to compare its selectivity versus neutral FITC-Dextran 70 or anionic FITC-CM-Dextran 70.
