Ready-to-use ELISA kits are available for the detection of cytidine 5'-triphosphate synthase, an alias of the protein, CTP synthase 1. The official gene symbol is CTPS1. The protein has a mass of 66.7 kDa and length of 591 residues. It is a member of the CTP synthase family and may be known by other names, including: IMD24, GATD5, cytidine 5-prime triphosphate synthetase, cytidine 5'-triphosphate synthetase, UTP--ammonia ligase 1, and CTP synthetase 1.
