Tween-20 pretreatment increases recovery of cerebrospinal fluid (CSF) amyloid-β 1–42 (Aβ1–42) from 0.1-ml and 0.5-ml aliquots but fails to consistently normalize sample volume-associated difference between aliquots. a CSF Aβ1–42 concentrations from three patients with Alzheimer’s disease as measured by the AlzBio3 immunoassay. b CSF Aβ1–42 concentrations from the same patients, as measured by the MSD Aβ1–42 assay
