Dolichos Biflorus Agglutinin (DBA), Fluorescein (FL-1031)

Description

Dolichos biflorus agglutinin has a carbohydrate specificity toward α-linked N-acetylgalactosamine.  It has been used to establish secretor status in blood group A individuals by hemagglutination inhibition techniques and for blood typing. This lectin has also been used as a general marker of developing renal collecting ducts.

Fluorescein labeled Dolichos biflorus agglutinin has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes. The excitation maximum is at 495 nm and the emission maximum is at 515 nm.
