摘要：Three fluorescein-labeled lectins have been shown to exhibit specificity for the surface of cells in different layers of the epidermis in the newborn rat. An isolectin from seeds of Bandeiraea simplicifolia with specificity for alpha-D-galactosyl end groups labeled the basal and lower spinous cells; a lectin from Ulex europaeus exhibiting specificity for alpha-L-fucosyl units outlines the surface of spinous cells, and a second lectin from B. simplicifolia, with specificity for N-acetyl-D-glucosamine, labels the cornified cells. Appropriate blocking experiments have confirmed the specific nature of the binding.
