Blood group substances as
The level of cellular differentiation of human oral, sulcular, and junctional epithelium was compared by immunohistochemical analysis of cell membrane-associated blood group-specific carbohydrates. Identification of the blood group A-specific carbohydrate and its two immediate precursor substances, type 2 chain H and N-acetyllactosamine. was accomplished by an indirect immunofluorescence techni...
متن کاملBlood-group-Ii-active gangliosides of human erythrocyte membranes.
More than ten new types of gangliosides, in addition to haematoside and sialosylparagloboside, were isolated from human erythrocyte membranes. These were separated by successive chromatographies on DEAE-Sephadex, on porous silica-gel columns and on thin-layer silica gel as acetylated compounds. Highly potent blood-group-Ii and moderate blood-group-H activities were demonstrated in some of the g...
متن کاملAN AEROBIC SOIL MICROORGANISM WHICH DECOMPOSES BLOOD GROUP SUBSTANCES II. : Effect of Cell-Free Extracts on Blood Group Substances.
Cell-free extracts of a number of microorganisms have been shown to possess enzymatic activity against blood group substances. Thus, enzymes of Bacillus fulminans, isolated by Iseki and Tsunoda (1952), were found to attack O(H) but not A or B substances. Extracts from strains of Lactobacillus bifidus, var. penn, have been shown (Springer et al., 1954; Gyorgy et al., 1954) to break down A, B, an...
متن کاملHisto-blood group antigen-like substances of human enteric bacteria as specific adsorbents for human noroviruses.
Histo-blood group antigens (HBGAs) have been suggested to be receptors or coreceptors for human noroviruses (HuNoVs) expressed on the intestinal epithelium. We isolated an enteric bacterium strain (SENG-6), closely related to Enterobacter cloacae, bearing HBGA-like substances from a fecal sample of a healthy individual by using a biopanning technique with anti-HBGA antibodies. The binding capac...
متن کاملIdentification of human erythrocyte blood group antigens on decay- accelerating factor (DAF) and an erythrocyte phenotype negative for daf
Decay accelerating factor (DAF) is a glycoprotein present on the surfaces of many types ofcells in contact with plasma, including erythrocytes, leukocytes, and platelets (reviewed in reference 1). A small amount of DAF is also present in serum. Numerous investigators have demonstrated that DAF inhibits the action of C3 convertases on cell surfaces, and its absence has been shown to be at least ...
