TABLE 1.

Stokes radius r for 50 μm monomeric AS, 50 μm Hsp90, and soluble oligomers obtained by agitation of AS in the presence of Hsp90 (AS:Hsp90 = 1:2)

For preparations of mature fibrils, little residual monomeric AS and no higher sized species were detectable in solution after sample centrifugation (data not shown).

	Stokes radius r
	nm
Monomeric AS	3.0 ± 0.2a
Hsp90	7.1 ± 0.6
AS agitated in the presence of Hsp90	14.8 ± 1.7

^a Value reported in literature: 3.2 nm (41).
