Maackia Amurensis Lectin I (MAL I), Biotinylated

Maackia amurensis lectin I binds to galactose (beta-1,4) glcNAc, but galactose-tolerant n-acetyllactoamine is replaced by sialic acid. However, when substituted with sialic acid at position 6 of galactose, MAL I does not appear to bind to this structure. Biotinylated kiwifruit lectin binds the appropriate amount of biotin to provide the best staining properties for this lectin. This conjugate contains essentially no unconjugated biotin and is preserved with sodium azide.
