Cayman Chemical MItoCheck Complex I ActIvIty
Complex I (NADH dehydrogenase/NADH:ubiquinone oxidoreductase) is one of the major sites of electron entry into the mitochondrial electron transport chain (ETC). Complex I catalyzes the 2 electron oxidation of NADH followed by the reduction of ubiquinone (Q) to form ubiquinol (QH2), and ultimately the reduction of the terminal electron acceptor, O2. During the passage of electrons from NADH to Q, the translocation of four protons (H+) from the mitochondrial matrix to the intermembrane space occurs, contributing to the chemiosmotic proton gradient, which is required for oxidative phosphorylation. Cayman's MitoCheck Complex I Activity Assay allows for the activity of complex I to be determined without the need to isolate mitochondria or pre-incubate with antibodies. The rate of NADH oxidation is measured by a decrease in absorbance at 340 nm and is proportional to the activity of complex I.
Cayman Chemical MItoCheck CItrate Synthase A
The condensation of the dicarboxylate oxaloacetate and acetyl CoA to the tricarboxylate citrate is catalyzed by citrate synthase. It is within this reaction that carbon molecules (as acetyl CoA) obtained from pyruvate oxidation are fed into the tricarboxylic acid (TCA or citric acid) cycle. As a mitochondrial enzyme, citrate synthase is commonly used as a normalization factor for mitochondrial protein, but can also be used as a biomarker for mitochondrial content in a tissue homogenate. Cayman's MitoCheck Citrate Synthase Activity Assay Kit allows for the simple and convenient determination of citrate synthase activity from isolated mitochondria, tissue, or cell homogenates. This assay measures the production of SH-CoA by monitoring the absorbance of Citrate Synthase Developing Reagent at 412 nm in a convenient 96-well format.

Electron Microscopy Sciences QuantomiX WetSEM QX -102 Starter Kit
The QX-102 Capsules are used for scanning electron microscope imaging of wet materials and biological samples, including liquid foods, cosmetics, oils, and paints, particles in solutions, adherent and non-adherent human and animal cells, and microorganisms. The samples can be visualized either directly or by following appropriate contrast enhancement staining or labeling procedures. The capsule serves as a cell culture dish, specifically designed for the SEM . No coating or embedding of the sample are required, enabling electron microscopy imaging with easy sample preparation comparable to light microscopy. Kit includes QX-102 Capsules and necessary accessories.
