Characteristics of binding between reagent-strip indicators and urinary proteins.
We describe the binding characteristics of two indicator dyes that are widely used in commercial "dip-stick" indicators for protein in urine. Binding was studied by both gel filtration chromatography and by spectrophotometric titrations. The results demonstrate that the well-known lack of sensitivity of these strips to proteins other than albumin relates to the number and affinity of binding si...

deficiency. It is not applicable to newborn or mass screening with use of ifiterpaper specimens, but is satisfactory for liquid urine screening. In one variant of sulfite oxidase deficiency, due to a defect of its molybdate cofactor metabolism, the concentration of uric acid in serum is decreased. Thus, an unexplained low serum uric acid, especially in a young patient with neurologic abnormalit...
متن کاملDiagnostic Accuracy of Cerebrospinal Fluid Amyloid-β Isoforms for Early and Differential Dementia Diagnosis.
BACKGROUND Overlapping cerebrospinal fluid biomarkers (CSF) levels between Alzheimer's disease (AD) and non-AD patients decrease differential diagnostic accuracy of the AD core CSF biomarkers. Amyloid-β (Aβ) isoforms might improve the AD versus non-AD differential diagnosis. OBJECTIVE To determine the added diagnostic value of Aβ isoforms, Aβ(1-37), Aβ(1-38), and Aβ(1-40), as compared to the ...
متن کاملCerebrospinal fluid biomarkers in Alzheimer's disease: Diagnostic accuracy and prediction of dementia
INTRODUCTION Guidelines for the use of cerebrospinal fluid (CSF) biomarkers in the diagnosis of Alzheimer's disease (AD) establish that each laboratory must use internally qualified cutoff values. We determined the concentrations of biomarkers that discriminate cases from controls and combinations that predict the progression to dementia in a Brazilian cohort. METHODS Concentrations of amyloi...
متن کاملApolipoprotein E genotype and the diagnostic accuracy of cerebrospinal fluid biomarkers for Alzheimer disease.
IMPORTANCE Several studies suggest that the apolipoprotein E (APOE) ε4 allele modulates cerebrospinal fluid (CSF) levels of β-amyloid 42 (Aβ42). Whether this effect is secondary to the association of the APOE ε4 allele with cortical Aβ deposition or whether APOE ε4 directly influences CSF levels of Aβ42 independently of Aβ pathology remains unknown. OBJECTIVE To evaluate whether the APOE geno...
