Aminoaciduria in childhood
Paper partition chromatography has been used extensively to study the aminoacid excretion in the urine of healthy children, of newborn infants and of patients suffering from eight different metabolic disorders. The purpose of this investigation was to discover the aminoacid pattern in the urine and …

Monosialylgangliosides from human meconium: characterization using specific anti-oligosaccharide antibodies
… of this fraction were detected after thin layer chromatography by immuno-staining with specific anti-oligosaccharide sera. The monosialylganglioside fraction of human meconium was subjected to ozonolysis and alkali-fragmentation and the resulting ganglioside-derived oligosaccharides were reduced …

Variable Tnf-α Production By Murine Macrophages to a Cell Wall Extract of Candida Albicans
… shown to contain mannose by acid hydrolysis and paper chromatography. Murine peritoneal (PMφ) and alveolar (AMφ) macrophages were collected and treated with varying concentrations (0.05-1000 μg/ml) of mannan. Controls included LPS-treated cells and inhibition studies using 2% D-mannose and …

Structural and Metabolic Studies of Glycosaminoglycans (Sulfatase, Hydrazine, Mucopolysaccharidosis)
… were reduced with NaB('3)H(,4) and separated by paper chromatography and anion exchange HPLC. Mono- and disulfated disaccharides from keratan sulfate (KS), the chondroitin sulfates (CS), and dermatan sulfate (DS) were identified. The relative amounts of CS and DS disaccharides released following …

Isolation of a human milk sialyloligosaccharide by affinity chromatography with wheat germ agglutinin (WGA)
Lectin affinity chromatography has been applied to the separation of the sialyloligosaccharides of human milk. A human milk sialyloligosaccharide fraction was tritium labeled and applied to a highly substituted WGA-agarose column (20 mg/ml). Only a single component from the complete …
