Anti-SFTPB antibodies are used in the immunodetection of the protein surfactant protein B. In humans, the canonical protein has a reported length of 381 amino acid residues and a mass of 42.1 kDa. It has been described to be a secreted protein. It is notably expressed in the lung. SFTPB is known to be involved with organ morphogenesis and the metabolism of lipids. Post-translational modifications have been described, including glycosylation. The SFTPB gene has been associated with the disease, Pulmonary surfactant metabolism dysfunction. Synonyms for this target antigen include SFTB3, SFTP3, SMDP1, SP-B, pulmonary surfactant-associated protein B, and PSP-B. SFTPB gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of Sftpb antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
