Anti-SARS antibodies enable researchers to detect and measure the SARS antigen in biological samples. This target is a reported synonym of the SARS2 gene, which encodes seryl-tRNA synthetase 2, mitochondrial. This protein is known to catalyze the attachment of serine to tRNA(Ser). The human version of SARS has a canonical amino acid length of 518 residues and a protein mass of 58.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. SARS is a member of the Class-II aminoacyl-tRNA synthetase protein family. Over 80 citations in the literature describe the use of SARS antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
