Affinity chromatography on anticlusterin-Sepharose of the crude protease preparation eluted from the IgG-AffiGel column with NaSCN.
(A) vWF-cp activity in the protease preparation before application onto anticlusterin column (a), in the breakthrough fraction (b), and in the NaSCN-eluted fraction (c). The activity was bound in the anticlusterin column and released during elution with NaSCN. (B) Dot blot analysis of the same 3 samples, using dilutions (dil) 1:2 to 1:32, shows complete clusterin removal on anticlusterin-Sepharose and its dissociation in the chaotropic medium.
