Source / Purification
Monoclonal antibody is produced by immunizing animals with human liver fixed in formalin.
Background
Carbamoyl phosphate synthetase 1 (CPS1), a rate-limiting enzyme in the urea cycle, catalyzes the conversion of ammonia and bicarbonate to carbamoyl phosphate in mitochondria. Non-small cell lung carcinoma (NSCLC) cells with oncogenic KRAS and loss of the tumor suppressor LKB1 express CPS1 and depend on this enzyme for growth. CPS1 maintains pyrimidine/purine balance in these cancer cells. Silencing CPS1 reduces the pyrimidine to purine ratio and stalls DNA synthesis, leading to DNA damage and cancer cell death (1). In addition, the tumor suppressor p53 represses the expression of urea cycle enzymes CPS1, OTC, and ARG1 and, therefore, causes the accumulation of ammonia, suppressing cancer growth (2). Furthermore, research studies suggest that hypermethylation-mediated downregulation of CPS1 expression may contribute to the progression of normal hepatocytes to hepatocellular carcinoma (HCC) (3). CPS1 was identified to be the antigen detected by Hep Par-1 antibody (4).
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
