Lectin staining studies on follicular atresia in house rat (Rattus rattus).

Topographic distribution of terminal and intercalary carbohydrate moieties were studied using horseradish peroxidase conjugated Glycine max (GMA), Arachis hypogea (PNA), Lotus tetragonolobus (LTA), Bandirarea simplicifolia (BSA), and Dolichos biflorus (DBA) agglutinins. N-Gal NAc, alpha-D-Gal, alpha-L-Fuc, D-Gal (beta-1-3)-D-Gal NAc, and alpha-beta-D Gal NAc linked glyco-conjugates were exposed during follicular atresia in oocyte, zona pellucida and granulosa cells. Theca interna and interstitial gland tissue revealed homology in lectin binding.
