Fig. 7From: Human Lung Surfactant Protein A Exists in Several Different Oligomeric States: Oligomer Size Distribution Varies between Patient GroupsComparison of the distributions of SP-A oligomers in BAL fluids from the three patient groups studied. The content of SP-A as hexamers, tetramers, and lower-order structures was calculated as a percentage of total SP-A. Division between forms was done on the basis of the pooled fractions as described in Figure 2.Back to article page
