Anti-spb antibodies are used in antigen-specific immunodetection in biological samples. The target spb is a known alias name of the protein surfactant protein B, encoded by the SFTPB gene in humans. This 381-amino acid residue protein is known to be involved in organ morphogenesis and the metabolism of lipids, among other biological processes. The protein is secreted and features glycosylated post-translational modifications. It is reported to be expressed in the lung. Other synonyms for spb include PSP-B, SFTB3, and SFTP3. Indicated applications for spb antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
