Preparation and Storage
Stability and Storage
Shipped on dry ice. Upon delivery aliquot and store at -80ºC. Avoid freeze / thaw cycles.
Constituents: 0.3% Glutathione, 0.79% Tris HCl
18 kDa pulmonary-surfactant protein
6 kDa protein
Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter.
Involvement in disease
Pulmonary surfactant metabolism dysfunction 1
Respiratory distress syndrome in premature infants
Contains 1 saposin A-type domain.
