Vector Laboratories Dolichos Biflorus Agglutinin (DBA) Fluorescein-labeled 2 mg
Supplier: Vector Laboratories FL10312
Dolichos biflorus agglutinin (DBA) binds α-linked N-acetylgalactosamine. A glycoprotein consisting of four subunits of approximately equal size and with a molecular weight of about 111 kDa, DBA is used to establish secretor status in blood group A individuals by hemagglutination inhibition techniques and for blood typing. It has also been used as a general marker of developing renal collecting ducts. This fluorescein-labeled DBA features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 495 nm, emission 515 nm). Supplied as a solution essentially free of unconjugated fluorophores, it is preserved with sodium azide. The recommended inhibiting/eluting sugar is 200 mM N-acetylgalactosamine.
