Urine Iodine determination Kit
Iodine is an essential constituent of the thyroid hormones (T4, T3). The major role of iodine in nutrition arises from the important part played by the thyroid hormones in the growth and development of humans and animals. Although goiter is indeed the visually obvious and familiar feature of iodine deficiency, of other consequences of iodine deficiency enhanced knowledge has led to the many the effects of iodine deficiency on growth and development being now denoted by the term iodine-deficiency disorders (IDD). The most important information in the determination of the status of iodine nutrition of a given population comes from the measurement of the urinary iodine. Therefore, assessment of iodine deficiency and monitoring of iodine supplementation programs demands rapid, simple and cost-effective methods for the determination of urinary iodide concentrations.

Nitric Oxide Assay Kit
Trusted by researchers to measure nitric oxide levels in various biological samples
Nitric oxide (NO) is a colorless gas and one of the main oxides of nitrogen. This compound is a free radical with an unpaired electron and acts as one of the important messengers in the path of cellular messaging. Nitric oxide is made by various enzymes that make nitric oxide (NOS) from compounds such as L-arginine, oxygen and NADPH. Various studies have shown the relationship between NO and various diseases, and in recent years, research in this field has attracted the attention of researchers. NO Detection Kit, Product of PTC, a simple, sensitive, repeatable and standard colorimetric method for measuring NO levels in various biological samples such as plasma, serum, saliva, urine, tissue, cell culture supernatant, cell Provides lysis and other biological fluids. Because the half-life of NO is very short, its values are determined indirectly by measuring the levels of nitrite and nitrate. The measurement method in this kit generally consists of two steps. In the first step, endogenous nitrite levels are determined. In the second step, using a reducing agent, nitrate is converted to nitrite and total nitrite values are measured. To calculate the amount of nitrate, the amount of endogenous nitrite is subtracted from the total nitrate. Nitrite and nitrate, with a dye reagent, form a pink compound that has a maximum light absorption at 540 or 550 nm. The detection range of this kit is about 3.12-100 µ and its sensitivity or detection limit is 1 .M.

Total Antioxidant Capacity (TAC)
Trusted by researchers to measure the total antioxidant capacity of various biological samples
Antioxidants play a very important role in eliminating and preventing the formation of free radicals and other toxic oxidizing species. In general, there are three main groups of antioxidant species: enzyme systems (GSH Reductase, catalase, and peroxidase), small molecules (ascorbate, uric acid, GSH, vitamin E) and proteins (Albumin and transferrin). Different antioxidants differ in their ability to reduce. Measurement of non-enzymatic antioxidant capacity in biofluids and other samples provides an indication of the total capacity to neutralize reactive oxygen species (ROS), resist oxidative damage, and combat oxidative stress-related diseases. In some cases, the antioxidant function of proteins is desired, while in other cases, the antioxidant function of small molecules is required. The full antioxidant capacity kit from the Iranian company PTC provides a simple and sensitive colorimetric method for measuring a combination of small antioxidant molecules and antioxidant proteins or small antioxidant molecules alone. Slowly In this kit, Cu2 + ions are converted to Cu + by small molecules and antioxidant proteins. A protein mask inhibits the reduction of Cu2 + ions, and at this point only the antioxidant properties of small molecules can be analyzed. Using a colorimetric probe, the Cu + ion will show the maximum absorption at 490 nm, which is directly related to the total antioxidant capacity. The detection range of this kit is 0.2-125 mM and its sensitivity or detection limit is approximately 0.1 mM.

Glutathione Peroxidase Activity Assay Kit
Researchers trusted to measure glutathione peroxidase activity in various biological samples
Glutathione peroxidase (GPX) is the general name of a family of enzymes with peroxidase activity whose main role is to protect the body from oxidative damage. The biochemical function of glutathione peroxidase is to reduce lipid hydroperoxidases to their corresponding alcohols and to reduce hydrogen peroxide to water. Studies have shown low serum and plasma levels of this enzyme in diseases such as vitiligo, MS and type 2 diabetes. Due to the increasing prevalence of these patients, research in this field has also increased. GPX Enzyme Activity Assay Kit, manufactured by the Iranian company PTC, is a simple, sensitive, reproducible and standard colorimetric method for measuring GPX activity in various biological samples such as plasma, serum, urine, tissue, cell culture supernatant, cell lysed and provides other biological fluids. In this kit, the GPX enzyme uses GSH as the final electron donor and converts it to GSSG, the remaining GSH reduces DTNB and produces a yellow color with a maximum absorption at 412 nm. The intensity of absorption of this color will be inversely proportional to the activity of GPX. The detection range of this kit is about 20-500 U / mL and the sensitivity or detection limit is 5 U / mL.

Catalase Activity Assay Kit
Trusted by researchers to measure the activity of the enzyme catalase in various biological samples
Catalase (CAT) is a peroxisomal enzyme with four Heme-containing polypeptide chains and plays a very important role in the breakdown of oxygenated water (H2O2). This enzyme converts H2O2 to water and oxygen and inhibits its toxic effects on living cells. In eukaryotic cells, hydrogen peroxide is formed as a result of various oxidation and superoxide dismutase reactions. Accumulation of hydrogen peroxide inside cells leads to oxidation of DNA, proteins, fats, resulting in mutations and cell death. Therefore, the removal of this toxic compound from the cells by the enzyme catalase has a protective role against oxidative damage. In humans, large amounts of this enzyme are found in the liver, kidneys and red blood cells. Catalase Enzyme Assay Kit, manufactured by the Iranian company PTC, is a simple, sensitive, reproducible and standard colorimetric method for measuring catalase activity in various biological samples such as plasma, serum, saliva, semen, tissue, lysed cells and others.
