Application

Lectin from Dolichos biflorus (horse gram) has been used:to characterize mouse uterine natural killer (uNK) cellsin double staining with lectins to localize nuclear factor-κB (NF-κB) activationas a species-specific gonocyte marker for the determination of donor cell colonizationto label undifferentiated spermatogonia/cat testicular tissue

Biochem/physiol Actions

DBA has anti-A₁ human blood group specificity, useful for distinguishing between A₁ and A₂ blood types. DBA has strong anti-Cad activity, and has an affinity for terminal N-acetyl-α-D-galactosaminyl residues. Conjugates are prepared from affinity purified lectin.

Dolichos biflorus agglutinin (DBA) possesses binding activity for which it is used as a marker binucleate cells and can indicate the state of their differentiation. It serves as a label for primordial germ cells (PGCs), gonocytes, pre-spermatogonia and spermatogonia.

General description

Lectin from Dolichos biflorus (horse gram) is a heterotetrameric glycoprotein with a molecular mass of around 113 kDa. Dolichos biflorus agglutinin (DBA) is specific for terminal α-linked N-acetyl-D-galactosamine (GalNAc). It is a dietary lectin.
