blot force = 1 N; blot time = 6 s; waiting time = 27 s.
Freshly purified ARISCdC(E33A) (at 0.8 mg/mL) was mixed with 1.5-fold molar excess of K63-linked heptaUb (Ub7) chains, and incubated in the presence of 0.025% (v/v) glutaraldehyde (Sigma-Aldrich) at room temperature for 4 min. Cross-linking reactions were then quenched by the addition of 100 mM Tris-HCl pH 7.5 prior to cryo-EM grids preparation.
