Anti-SFTP3 antibodies enable researchers to detect and measure the SFTP3 antigen in biological samples. This target is a reported synonym of the SFTPB gene, which encodes surfactant protein B. This protein is known to function in organ morphogenesis and the metabolism of lipids, among other biological roles. The human version of SFTP3 has a canonical amino acid length of 381 residues and a protein mass of 42.1 kilodaltons. It is reported to be a secreted protein that is notably expressed in the lung. Other names for this target antigen include PSP-B and SFTB3. Indicated applications for SFTP3 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
