Abstract
Subject headings
Close
- A targeted mass spectrometric assay was developed for identification and quantification of apoE isoforms (apoE2, E3 and E4), and it was utilized for screening of samples from AD patients (. n=. 39) and patients with other neurodegenerative disorders (. n=. 38). The assay showed good linearity with LOQ corresponds to total apoE concentration of 0.8 and 40. ng/mL in CSF and plasma/serum, respectively. We identified apoE phenotypes with 100% accuracy in clinical samples. We found strong association between genotypes of the individuals and their apoE levels in blood; ε4 allele carriers had significantly lower apoE levels in blood than non-carriers. © 2015.
