Griffonia Simplicifolia Lectin I (GSL I) Isolectin B4 Native Protein Summary

• Description: A biologically active protein corresponding to Griffonia Simplicifolia Lectin I (GSL I) Isolectin B4.
  

  Source: Griffonia (Bandeiraea) simplicifolia seeds
  
  GSL I-B4 isolectin contains only the B subunits. It is a useful marker for endothelial cells from nonprimates such as mouse, rat, rabbit, and goat as well as a marker for non-peptidergic unmyelinated primary afferent neurons. This “B”-rich lectin preferentially agglutinates blood group B cells and is specific for a-galactose residues.
  
  For reconstituted liquid, storage at 4 C with 0.08% sodium azide can be used. For preserving solutions stored at 4C, 0.08% sodium azide can be used. Specific for galactose. Inhibitors: 500 mM galactose or 100 mM raffinose.

Background

GSL I is a family of glycoproteins with molecular weights of approximately 114 kDa. There are two types of subunits, termed A and B , with slightly different molecular weights. These subunits combine to form tetrameric structures, resulting in five isolectins. The A-rich lectin preferentially agglutinates blood group A erythrocytes and thus appears to be specific for alpha-N-acetylgalactosamine residues, while the B-rich lectin preferentially agglutinates blood group B cells and is specific for alpha-galactose residues. Our GSL I is a mixture of the five isolectins. GSL I has been reported to bind several glycoproteins including laminin.

GSL I-B4 isolectin contains only the B subunits. It is a useful marker for endothelial cells from non-primates such as mouse, rat, rabbit, and goat as well as a marker for non-peptidergic unmyelinated primary afferent neurons.

Inhibiting Sugar: 500 mM galactose or 100 mM raffinose
