The histochemistry of galactose residues of complex carbohydrates as studied by peroxidase-labeled Ricinus communis agglutinin. 1977

K Yamada, and S Shimizu

A peroxidase-labeled Ricinus communis agglutinin diaminobenzidine (PO-RCA-DAB) procedure has been utilized to determine the light microscopic localization of galactose residues of complex carbohydrates in a variety of tissues from different vertebrate species. In the same tissues, the localization of mannose and glucose residues was studied by means of a concanavalin A peroxidase diaminobenzidine (Con A-PO-DAB) procedure for comparison. The distribution pattern of galactose residues was found to be in distinct contrast with that of mannose and glucose residues in connective and epithelial tissues such as those involved in the umbilical cord, cartilage, aorta, comb, thyroid gland, submaxillary gland, duodenum, jejunum, colon and gill of various vertebrates. The results of the present study indicate that the PO-RCA-DAB procedure is useful in providing a means of dividing periodic acid-Schiff reactive neutral complex carbohydrates into subgroups in comparison with the intensity of their Con A-PO-DAB reaction in the histochemistry of complex carbohydrates.

D010947	Plants, Toxic	Plants or plant parts which are harmful to man or other animals.	Plants, Poisonous,Plant, Poisonous,Plant, Toxic,Poisonous Plant,Poisonous Plants,Toxic Plant,Toxic Plants
D002241	Carbohydrates	A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES.	Carbohydrate
D005690	Galactose	An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012278	Ricinus	A plant genus of the family Euphorbiaceae. The seed of RICINUS COMMUNIS is the castor bean which is the source of CASTOR OIL; RICIN; and other LECTINS.
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
