Effect of consecutive tube transfer on Aβ38 and Aβ40. A) Replication: data represent three assays. Neat CSF Aβ38 concentration decreases linearly with consecutive transfer between tubes. Tween 20 mitigates the concentration decrease in the same CSF. Lines of the same type represent within and between plate replicates, separate days are not distinguished. B) Replication: data represent three assays. Neat CSF Aβ40 concentration decreases linearly with consecutive transfer between tubes. Tween 20 mitigates the concentration decrease in the same CSF. Lines of the same type represent within and between plate replicates, separate days are not distinguished. Aβ38, amyloid beta 38; Aβ40, amyloid beta 40; CSF, cerebrospinal fluid.
