Geodia cydonium : Sponge

Molecular structure of

Geodia cydonium

Lecster ID:249 Edit Entry
Source Organism:Sponge
Species:Geodia cydonium
Common Nomenclature:
Index Nomenclature:LECi.Geo.Cyd.xx.Xga1
Characterization Notes:
Biological Activity:In the histochemical system GCA displayed no blood group specificity and labeled red blood cells, the vascular endothelium, and epithelial cells showing blood group antigen expression independent of the ABH blood group status. However, inhibition of GCA reactivity by simple sugars and complex carbohydrate s demonstrated tissue-specific differences of lectin binding related to the ABH blood group status of the tissue and revealed information on the structural requirements of the histological lectin binding site. Tissues that totally lacked blood group antigens or that expressed only the H-antigen disclosed a GCA reactivity which was completely inhibited by lactose. In contrast, tissues that expressed blood group A- or blood group B-antigen exhibited a lactose-resistant lectin binding which was inhibited only by water-soluble blood group substance A from peptone A and by bovine glycophorin but not by other complex carbohydrate s, including human glycophorin and human asialoglycophorin.
