General description

Nicotinamide adenine dinucleotide (NAD) is an enzymatic cofactor involved in many redox reactions. NAD functions as an electron carrier, cycling between the oxidized (NAD) and reduced (NADH) forms. In addition to its role in redox reactions, NAD plays critical roles in ADP (adenosine diphosphate)-ribosylation reactions and as a substrate for sirtuins.


NAD/NADH Quantitation Kit has been used to quantify NAD+/NADH influenced by SIRT1 (sirtuin 1) activity (associated with ischemia-reperfusion injury) in the presence of trimetazidine.


Suitable for the detection of NADH and NAD in animal tissues (liver, kidney etc.), cell culture (adherent or suspension cells), serum or urine.


The NAD/NADH Quantification Kit provides a convenient tool for sensitive detection of the intracellular nucleotides, NAD (nicotinamide adenine dinucleotide) and NADH, and their ratio without the requirement to purify NAD/NADH from samples. This assay is specific for NAD and NADH, and does not detect NADP or NADPH. NADt (NAD and NADH) or NADH are quantified in a colorimetric assay (450 nm).

Glutamine Metabolism is Dysregulated in Many Cancer Cells

Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.

Aerobic Glycolysis and the Warburg Effect

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
