Anti-Es31 antibodies enable researchers to detect and measure the Es31 antigen in biological samples. This target is a reported synonym of the CES3 gene, which encodes carboxylesterase 3. This protein is known to function in metabolic processes, among other biological roles. The human version of Es31 has a canonical amino acid length of 571 residues and a protein mass of 62.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER of cells and notably expressed in many tissues, such as the appendix and colon. Es31 is a member of the Type-B carboxylesterase/lipase protein family. Indicated applications for Es31 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
