The quantitative determination of glycosaminoglycans in urine with Alcian Blue 8GX.
1. The effect of MgCl(2) concentration on the interaction of Alcian Blue 8GX and glycosaminoglycans in the urine of patients with mucopolysaccharidosis was studied by using a new quantitative micro method for the measurement of Alcian Blue-glycosaminoglycan complexes. This provided a means of measuring the critical electrolyte concentrations of urinary glycosaminoglycans. 2. Theoretical conside...

متن کاملDimethylmethylene blue-based spectrophotometry of glycosaminoglycans in untreated urine: a rapid screening procedure for mucopolysaccharidoses.
Glycosaminoglycans (GAGs) are measured in urine to screen for mucopolysaccharidoses. Other assay procedures are only qualitative (spot tests), can give false-negative results (spot tests, turbidity tests), or are relatively laborious (uronic acid-carbazole test). The present spectrophotometric procedure, based on the color reaction with dimethylmethylene blue (DMB), can be performed directly on...
متن کاملAn assay evaluation of the methylene blue method for the detection of anionic surfactants in urine.
Adding detergent to urine intended for drug testing is one of many ways to adulterate the specimen. This modified methylene blue procedure allows the detection and quantitation of anionic surfactants in urine. One-hundred urine specimens that exhibited normal foaming when shaken gave anionic surfactant values lower than 36 microg/mL with a mean of 8.73 microg/mL. Most of the suspected adulterat...
متن کاملMutagenicity of dog urine determined by blue rayon extraction and the ultramicro forward-mutation method.
The mutagenicity of 15 household dog urine specimens were measured by the combination of blue rayon extraction and ultramicro forward-mutation method with Salmonella Typhimurium TM677 strain. A good dose-response relation was observed between the urine volume and mutation frequency. The minimum amount of urine required was 20 ml or less. The specific mutation frequency of urine greatly varied f...
