The levels of Aβ oligomers decrease, whereas those of Aβ monomers increase, when the void volume fraction of AD brain is incubated at 37°C^a

	Void volume preincubation			Void volume postincubation
	x-40	x-42	Oligomers	x-40	x-42	Oligomers
AD1	388	68	10,986	407	859	1401
AD2	105	249	2079	823	4017	29
AD3	165	59	984	771	104	71
AD4	19	57	9711	745	1993	39

^aSEC void volume fractions from 4 AD brains were analyzed using x-40 and x-42 monomer-preferring immunoassays, and the 1C22-3D6 oligomer-preferring immunoassay before and after 2 d incubation at 37°C.
