Abstract

Lamellar bodies isolated from rat lung contain all three classes of surfactant proteins, SP-A, SP-B and SP-C, as determined by immunoblot analysis. The amounts of the surfactant proteins present in lamellar bodies, determined by sandwich e.l.i.s.a. (SP-A) and fluorescamine assay (SP-B and SP-C) show that these organelles are highly enriched in the hydrophobic surfactant proteins SP-B and SP-C.
