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 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 کاملImmunochemical Studies on Blood Groups Xi. Species Differences among Blood Group a Substances*

By this technic human secretions and tissues of persons of blood group A (1, 2), the stomach linings of some individuals ...
متن کاملSTUDIES ON BLOOD GROUPS Ill . PROPERTIES OF PURIFIED BLOOD GROUP A SUBSTANCES FROM INDIVIDUAL
Some of the properties of blood group A specific substances from enzymatic digests of pools of hog stomachs have been presented in the preceding report (1). However, since it was known that not all hog stomachs show A activity (2), it was considered of interest to determine whether better products could be isolated from individual hog stomachs. When stomach linings from a number of individual h...
متن کاملAmphibian red blood cell ferritin.
Erythroid ferritin was isolated from tadpole red blood cells, an unusually abundant source, with an iron content of 12%. The apoprotein was characterized by sedimentation equilibrium studies, sodium dodecyl sulfate gel electrophoresis, and by determination of amino acid composition. Tadpole red cell apoferritin has a molecular weight of 478,000, a subunit size of 19,600, and an amino acid compo...
