Avidin-ferritin cytochemistry on lectin receptors of uterine epithelial cells in the rat.

Cytochemistry using biotinylated lectins and an avidin-ferritin label has been combined with freeze-fracture to study the relationship between surface carbohydrates and intramembranous particles in uterine epithelial cells. We find no structural relationship between the 2 classes of membrane components and consider the significance of this finding.
