Anti-h-cGAS antibodies are protein reagents that detect specific antigens. The h-cGAS antigen is another term for the human protein cyclic GMP-AMP synthase, encoded by the CGAS gene. The protein is a reported nucleotidyltransferase that catalyzes the formation of cyclic GMP-AMP (2',3'-cGAMP) from ATP and GTP and plays a key role in innate immunity. Canonically, it has an amino acid length of 522 residues and a mass of 58.8 kilodaltons. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm and it is reported to be expressed in the monocytic cell line THP1. The h-cGAS protein is a member of the Mab-21 protein family. Indicated applications for h-cGAS antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunoprecipitation.
