These QARS ELISA kits are immunodetection tools for measuring the levels of QARS in biological samples. QARS is an alias of the human QARS1 gene, which encodes the protein, glutaminyl-tRNA synthetase 1. Notably, QARS is known to play a role in brain development and the regulation of apoptosis, among other functions. The QARS1 protein is 775 amino acid residues in length and 87.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in fetal cerebral cortex, particularly in the ventricular zone, inner subventricular zone, outer subventricular zone, and cortical plate. Other names for this target antigen include GLNRS, MSCCA, and PRO2195. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
