Anti-GSTp antibodies enable researchers to detect and measure the GSTp antigen in biological samples. This target is a reported synonym of the GSTP1 gene, which encodes glutathione S-transferase pi 1. This protein is known to function in the cellular response to lipopolysaccharides and nervous system development, among other biological roles. The human version of GSTp has a canonical amino acid length of 210 residues and a protein mass of 23.4 kilodaltons. It is reported to be localized in the nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include DFN7, DFN7, and FAEES3. A number of GSTp antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
