Early OC-positive Aβ(1-42) species becomes resistant to SDS over time. Freshly-isolated Aβ(1-42) from a SEC monomer fraction in F-12 medium without phenol red was stored at 4° C without disturbance over 24 days. Panel A. At chosen time points after isolation the Aβ(1-42) solution (final concentration 20 μM) was incubated with or without 1% SDS for 10 min at 25° C and then analyzed by dot blot with Ab9 and OC antibodies. Panel B. Thioflavin T fluorescence measurements were taken of stored Aβ(1-42) solution at various time points.
