General description

Surfactant Protein B (SP-B) is mostly composed of phospholipids, but also incorporates essential proteins. It is necessary for pulmonary surfactant function and the alveolar type 2 cell phenotype. SP-B deficiency has been known to cause congenital pulmonary alveolar proteinosis. SP-B is thought to protect lungs against endotoxin-induced inflammation. SP-B could be used as a clinical marker in chronic heart failure.

Specificity

This antibody recognizes Surfactant Protein B at the Saposin B-type 2 domain.

Immunogen

Epitope: Saposin B-type 2 domain
GST-tagged recombinant protein corresponding to human Surfactant Protein B at the Saposin B-type 2 domain.

Application

Immunohistochemistry Analysis: 1:200 dilution from a representative lot detected Surfactant protein B in clara cells in normal rat lung tissue.
