Anti-PAP1 antibodies enable researchers to detect and measure the PAP1 antigen in biological samples. This target is a reported synonym of the LPIN1 gene, which encodes lipin 1. This protein is known to function in insulin signaling pathways, among other biological roles. The human version of PAP1 has a canonical amino acid length of 890 residues and a protein mass of 98.7 kilodaltons, although 7 isoforms have been identified. It is reported to be localized in the nucleus, ER, and cytoplasm of cells and widely expressed in many tissue types. PAP1 is a member of the Lipin protein family. Some PAP1 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
