Griffonia Simplicifolia Lectin I (GSL I) isolectin B4, Fluorescein

Product Details

Griffonia Simplicifolia Lectin I (GSL I) isolectin B4, Fluorescein, 0.5 mg. GSL I is a family of glycoproteins with molecular weights of ~114 kDa tetrameric structures made from two subunit types (termed A and B) of slightly different molecular weights that result in five isolectins. The A-rich lectin agglutinates blood group A erythrocytes (specific for alpha-N-acetylgalactosamine residues), while the B-rich lectin agglutinates blood group B cells (specific for alpha-galactose residues). This GSL I is a mixture of the five isolectins. GSL I reportedly binds several glycoproteins including laminin. GSL I-B4 contains only B subunits and is a marker for endothelial cells from nonprimates (e.g., mouse, rat, rabbit, and goat) and for non-peptidergic unmyelinated primary afferent neurons. This product has an appropriate number of fluorochromes to provide optimum staining and is supplied essentially free of unconjugated fluorochromes. Excitation maximum: 495 nm; Emission maximum: 515 nm.
