Comparative Lectins Histochemical Study of Vertebrates' Retina.

Abstract

30 experimental animals of three species of vertebrates was used; 10 adult Carp fishes, 10 adult doves, and 10 adult Albino rats. Both eyes were taken. 5 paraffin sections were prepared from each eye with 6 µm thickness for histochemical study with 5 lectins which are: UEAI, PNA, SBA, Con-A, and LFA.The aims of the study were comparing the types of carbohydrates by lectin histochemistry that present in the retina of three vertebrates species habituating in different environmental conditions.This study found a clear variation in types of carbohydrates in each one of the ten layers of vertebrates' retina.
