Figure 1From: Role of viral hemagglutinin glycosylation in anti-influenza activities of recombinant surfactant protein DSize distributions of Met11, Ala160 SP-D. Molecular size distribution of an unfractionated Met11 rhSP-D preparation was determined using (A) analytical ultracentrifugation, and (B) atomic force microscopy. Both methods show a distribution of trimers, dodecamers and higher molecular weight multimers.Back to article page
