Iron Colorimetric Assay Kit (Ferrozine Method) Reference: JAI-CFE-005 Iron is a mineral (functioning as an enzyme cofactor) that plays an essential role in many biological processes. It is essential to nearly all known organisms. As a transition element it can form a range of oxidation states, the most common being Fe2+ (or ferrous iron) and Fe3+ (or ferric iron). Ingested iron is mainly absorbed in the form of Fe2+. The trivalent form and the heme-bound Fe2+-component of iron is reduced by vitamin C. Before passing into the plasma, it is oxidized by ceruloplasmin to Fe3+ and bound to transferrin to form a transferrin-iron complex. Iron is generally stored in the centre of metalloproteins, in the heme complex, and in oxygen carrier proteins. Iron-containing proteins participate in many reactions, often utilizing transitory changes in the oxidation state of iron to carry out chemical reactions. Iron is important for redox reactions, oxygen transport (e.g. hemoglobin), short-term oxygen storage (e.g. myoglobin) and energy generation. Iron deficiency has many adverse consequences, including anemia, hemochromatosis, chronic renal disease and in children, behavioral and learning disorders. Iron excess is toxic to the body, harming the heart, liver, skin, pancreatic islet beta cells, bones, joints, and pituitary gland. Maintaining proper iron balance is essential for maintaining homeostasis and health.

Magnesium Colorimetric Assay Kit (Xylidyl Blue-I Method) Reference: JAI-CMG-035 Magnesium (Mg2+) is one of the most abundant trace metals in living organisms, contributing to a variety of biological functions including ATP and nucleic acid processing, energy metabolism, and enzymatic function. Magnesium forms complexes with multiple molecules such as phospholipids and ATP. Approximately 69% of magnesium ions are stored in bone. The rest are part of the intermediary metabolism about 70% being present in free form while the other 30% is bound to proteins (especially albumin), citrates, phosphate, and other complex formers. The Mg2+ serum level is kept constant within very narrow limits. Regulation takes place mainly via the kidneys, especially via the ascending loop of Henle. Low serum levels of magnesium have been associated with metabolic syndrome, diabetes mellitus type 2, and hypertension.
Zinc Colorimetric Assay Kit (5-Br-PAPS Method) Reference: JAI-CZN-001 Zinc (Zn2+) is an essential trace element, vital for the health of animals, plants, and microorganisms . Zinc is found in hundreds of enzymes, is stored and transferred in metallothioneins, and serves as structural ions in transcription factors. Zinc is often coordinated to the sides chains of amino acids, such as aspartic acid, glutamic acid, histidine and cysteine and is involved in nucleid acid and protein synthesis. It is therefore a necessary complement for cell replication. In humans, zinc interacts with a variety of organic ligands, and has roles in nucleic acid metabolism, apoptosis, neurological development, signal transduction, and gene expression. Zinc deficiency is related to skin lesions, irritability, loss of hair, growth retardation and impaired immunological functions.
Total Antioxidant Capacity (PAO) Test Kit Reference: JAI-KPA-050 Oxidative stress plays on important role in various diseases and aging. The control of oxidative stress is expected to be useful to prevent diseases and aging.Oxidative stress is caused by the imbalance between reactive oxygen species (ROS) and antioxidant defense system. For accurate assessment of oxidative stress, measurement of ROS, oxidative damage and antioxidant activity may be essential. Recently, antioxidants as functional foods which scavenge ROS attract a great deal of attention.
MDM2 E3 Ligase TR-FRET Kit Reference: SBB-KF0030 South Bay Bio’s MDM2 TR-FRET Ubiquitin Kit provides a fast and sensitive method monitoring ubiquitin conjugation onto GST-MDM2 in solution, resulting from an enzymatic ubiquitin cascade without the need of running and staining an SDS gel. The kit enables continuous TR-FRET detection of ubiquitin chain formation onto MDM2 in a real-time detection setup, or in an end-point configuration if desired. TR-FRET uses the extended fluorescence emission decay lifetimes typical of rare-earth lanthanides to impart a short time-delay between FRET donor excitation and emission. This delay provides a means to separate “true” signal from short-lived background fluorescence, and reduce interference from compound fluorescence and other assay artifacts.
