Ready-to-use ELISA kits are available for the detection of Gravin, an alias of the protein, A-kinase anchoring protein 12. The official gene symbol is AKAP12. The kits can detect several species variants of the protein, including: human, bovine, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 191.5 kDa and length of 1782 residues, is reported to be cytoplasmic. It may be known by other names, including: myasthenia gravis autoantigen gravin, kinase scaffold protein gravin, AKAP 250, A-kinase anchor protein 250kDa, A kinase (PRKA) anchor protein 12, and A-kinase anchor protein 12, and SSeCKS.
