Anti-LRS antibodies enable researchers to detect and measure the LRS antigen in biological samples. This target is a reported synonym of the LARS1 gene, which encodes leucyl-tRNA synthetase 1. This protein is known to catalyze the specific attachment of an amino acid to its cognate tRNA in a two step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. The human version of LRS has a canonical amino acid length of 1176 residues and a protein mass of 134.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include HSPC192, ILFS1, and LARS. Indicated applications for LRS antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry.
