CPS1 Antibody / Carbamoyl-phosphate synthase 1, 20ug

Hepatocyte specific antigen antibody targets Carbamoyl-phosphate synthase 1 (CPS1), a mitochondrial enzyme that catalyzes the first and rate-limiting step of the urea cycle. Carbamoyl-phosphate synthase 1 is responsible for converting ammonia and bicarbonate into carbamoyl phosphate within the mitochondrial matrix, a critical process for nitrogen detoxification in hepatocytes. Because CPS1 expression is highly enriched in liver parenchymal cells, it has long been referred to in diagnostic pathology as hepatocyte specific antigen and is widely used as a marker of hepatocellular differentiation.<br><br>Hepatocyte specific antigen antibody, also referred to as Carbamoyl-phosphate synthase 1 antibody and mitochondrial carbamoyl phosphate synthase antibody in the literature, highlights the strong metabolic specialization of hepatocytes. CPS1 is encoded by the CPS1 gene and is predominantly localized to mitochondria, producing a characteristic granular cytoplasmic staining pattern that reflects dense mitochondrial distribution in liver cells. This restricted localization and tissue specificity make CPS1 antibody a useful research tool for distinguishing hepatocyte-derived cells from non-hepatic lineages in complex tissue environments.<br><br>Carbamoyl-phosphate synthase 1 plays a central biological role in amino acid metabolism and ammonia detoxification. Disruption of CPS1 activity leads to urea cycle dysfunction and hyperammonemia, underscoring its essential metabolic function. Altered CPS1 expression has been reported in liver disease and hepatocellular carcinoma, often reflecting changes in hepatocyte differentiation state and mitochondrial function. Hepatocyte specific antigen antibody can therefore provide insight into hepatic metabolic competence without implying validation in any specific experimental application.<br><br>The CPS1 protein belongs to the class I amidoligase family and contains multiple conserved catalytic domains that coordinate ATP-dependent reactions. Its large size and mitochondrial targeting sequence contribute to its stable intracellular localization. Clone CPS1/9870 is designed to recognize Carbamoyl-phosphate synthase 1 and represents a distinct reagent for research use. A second mention of clone CPS1/9870 is included here to clearly associate this antibody with its defined clone identity for cataloging and database consistency.<br><br>In research settings, hepatocyte specific antigen antibody complements nuclear hepatocyte markers by providing metabolic and mitochondrial context rather than transcriptional identity alone. Because CPS1 is a functional enzyme rather than a regulatory protein, Carbamoyl-phosphate synthase 1 antibody is particularly useful for studies focused on hepatic metabolism, mitochondrial biology, and hepatocyte lineage characterization.<br><br>For a validated reference of CPS1 expression in liver and hepatocellular tumors, see the <a href=../tds/cps1-antibody-carbamoyl-phosphate-synthetase-1-cps19859-v5677>CPS1 antibody clone CPS1/9859</a> with supporting IHC and western blot data.
