Description

Fluorescein isothiocyanate is used as fluorescent labeling reagent for proteins and for rapid identification of pathogens in fluorescent antibody technique. It is also used as a reagent for microsequencing of proteins and peptides (HPLC). On celite it is used for the labeling of fibrinogen.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
