A suspension of p-Tau (8µM) or A1-42 aggregate (25µM)
was sequentially diluted (1:25 to 1:6500 for p-Tau; 1:2.5 to 1:320
for A) with HBS buffer [containing 10% (v/v) DMSO and 10
µM Zn(NO3)2], and then each diluted solution was mixed with a
solution of1(100 nM) in HBS buffer. After incubation for 2.5 h
at 37°C, the fluorescence intensity (545 nm) of each solution was
measured using a fluorescence microplate reader (Infinite M200,
TECAN) with excitation at 490 nm.
