Anti-ET antibodies enable researchers to detect and measure the ET antigen in biological samples. This target is a reported synonym of the PCYT2 gene, which encodes phosphate cytidylyltransferase 2, ethanolamine. This protein is reported to be an ethanolamine-phosphate cytidylyltransferase that catalyzes the second step in the synthesis of phosphatidylethanolamine (PE) from ethanolamine via the CDP-ethanolamine pathway. The human version of ET has a canonical amino acid length of 389 residues and a protein mass of 43.8 kilodaltons, although 4 isoforms have been identified. It is reported to be widely expressed in many tissue types. ET is a member of the Cytidylyltransferase protein family. Indicated applications for ET antibodies listed below include ELISA and Western Blot.
