Citrate synthase, mitochondrial (UniProt: O75390; also known as EC:2.3.3.1; Citrate (Si)-synthase, ) is encoded by the CS gene (Gene ID: 1431) in human. Citrate synthase, a mitochondrial enzyme encoded by nuclear DNA, is a key catalytic protein in the tricarboxylic acid (TCA) cycle, often referred to as the Krebs cycle. It is an all-alpha protein composed of a single polypeptide chain folded into a large and a small domain. The active site resides in a cleft between these domains. Citrate synthase catalyzes the condensation of acetyl-CoA and oxaloacetate to form citrate, marking the first and rate-limiting step of the TCA cycle. This reaction is fundamental for cellular energy metabolism, as citrate synthesis facilitates the downstream production of reduced nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FADH2), which are essential electron carriers for oxidative phosphorylation. Its activity is tightly regulated and responsive to cellular metabolic demands. Beyond its canonical role in energy metabolism, citrate synthase participates in cytoplasmic pathways when citrate is exported from mitochondria. Cytoplasmic citrate is converted to acetyl-CoA and oxaloacetate by citrate lyase, supporting lipid biosynthesis and signaling cascades. In pathological contexts, altered citrate synthase activity has been linked to cancer metabolism, where its dysregulation contributes to tumor proliferation and survival by modulating metabolic fluxes and promoting anabolic processes. Protein-protein interactions of citrate synthase include its association with other mitochondrial electron transport chain complexes, suggesting a broader role in mitochondrial function beyond its enzymatic activity. Post-translational modifications, such as protein lactylation, have been shown to regulate its activity, highlighting its involvement in metabolic reprogramming under stress conditions. This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

KLH-conjugated linear peptide corresponding to 22 amino acids from the C-terminal of human Citrate synthase.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
