  • Overlay Peak curve showing HepG2 cells stained with CSB-MA006327A0m (red line) at 1:100. The cells were incubated in 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 1h at 4°C. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/100 dilution for 30min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.

Mice were immunized with the recombinant human CYC1 protein (85-325aa), followed by the isolation of B cells from the mouse spleen, the fusion of these B cells with myeloma cells, and the selection of hybridomas that produce CYC1 antibodies. The CYC1 antibody-generating hybridomas were cultured to collect the CYC1 monoclonal antibodies. The CYC1 monoclonal antibody specifically reacts with human and mouse species and is suitable for ELISA, WB, and FC applications. The antibody is purified using protein A affinity chromatography and has a purity of over 95%.

CYC1 plays a crucial role in cellular energy metabolism and cell death regulation. It participates in the transfer of electrons between complexes III and IV of the respiratory chain, which drives the proton gradient across the mitochondrial inner membrane necessary for ATP synthesis. CYC1 also regulates apoptosis, or programmed cell death, by modulating the release of cytochrome c from mitochondria, which triggers the activation of caspases and leads to cell death.

Target Background

Component of the ubiquinol-cytochrome c oxidoreductase, a multisubunit transmembrane complex that is part of the mitochondrial electron transport chain which drives oxidative phosphorylation. The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. The cytochrome b-c1 complex catalyzes electron transfer from ubiquinol to cytochrome c, linking this redox reaction to translocation of protons across the mitochondrial inner membrane, with protons being carried across the membrane as hydrogens on the quinol. In the process called Q cycle, 2 protons are consumed from the matrix, 4 protons are released into the intermembrane space and 2 electrons are passed to cytochrome c. Cytochrome c1 is a catalytic core subunit containing a c-type heme. It transfers electrons from the [2Fe-2S] iron-sulfur cluster of the Rieske protein to cytochrome c.
