AGGLUTININ- DBA, FITC 2 MG，L32474，Applied Biosystems

Dolichos Biflorus (Horse Gram) Agglutinin (DBA), fluorescein (FITC), is a bright-green DBA-fluorophor conjugate. DBA 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. It has also been used as a marker of cell surface change in murine embryonic stem cells during early differentiation.

• Very bright FITC conjugate detected with traditional FITC/GFP filter set, Ex/Em: 495/515 nm
• Applications: immunofluorescence, glycobiology
• Sugar specificity: N-acetylgalactosamine
• Inhibiting/eluting sugar: 200 mM N-acetylgalactosamine
