Phaseolus Vulgaris Erythroagglutinin (PHA-E), Biotinylated

Phasebean lectins are the name of a family of lectins, each consisting of four subunits. There are two different types of subunits. One of these appears to be primarily involved in red blood cell agglutination and is designated as the "E" subunit (red agglutinin). Another type is involved in lymphocyte agglutination and mitotic activity and is known as the "L" subunit (leukocyte lectin). These subunits combine to produce five isolates. Biotinylated PHA-E has the right amount of biotin binding to provide optimal staining properties for this lectin. This conjugate contains essentially no unconjugated biotin and is preserved with sodium azide.
