CsCl density gradient separation of HCP from plain dS VLP derived from recombinant H. polymorpha strain A#299 analyzed by Western blot. The ultracentrifugation tube was divided into 11 fractions with increasing density from fraction 1–11. Top: unspecific staining of proteins (Ponceau S). Bottom: anti-dS immunostaining using 7C12 mAB. M, molecular weight marker
