Pulmonary Surfactant Proteins — frequently asked
What are the surfactant proteins?
Four proteins are found in pulmonary surfactant. SP-B and SP-C are small hydrophobic peptides embedded in the lipid film, while SP-A and SP-D are large oligomeric collectins with collagen-like stalks and calcium-dependent carbohydrate recognition domains.
Why are they researched?
SP-B and SP-C are studied for their reported role in lowering alveolar surface tension and in surfactant film formation, while SP-A and SP-D are studied largely for innate immune functions including microbial binding, agglutination and modulation of inflammatory responses.
What forms are supplied?
SP-A and SP-D are typically offered as recombinant or purified proteins. SP-B and SP-C are highly hydrophobic, so they are commonly supplied as synthetic analogues or in solvent-compatible formulations that suit monolayer and lipid interaction work.
