Product category: Other equipment for clinical chemistry
Arylesterase Assay Kit
Paraoxonase-1 (PON1) s an hgh densty lpoproten (HDL)-assocated enzyme wth antoxdant and antatherogenc functons, protectng lpoprotens aganst oxdatve modficaton. It also catalyzes the hydrolyss of organophosphates such as paraoxon and aromatc carboxylc acd esters of fatty acds. It has been shown that serum paraoxonase actvty decrease n dabetes melltus, coronary artery dsease, hypercholesterolaema, ron deficcency anemma, hepatts, crrhoss, prostate cancer, tuberculoss and nfammmatons.

PON1, present n the sample, hydrolyses phenyl acetate to ts products whch are phenol and acetc acd. The produced phenol s colormetrcally measured va oxdatve couplng wth 4-amnoantpyrne and potassum ferrcyande. Nonenzymatc hydrolyss of phenyl acetate was subtracted from the total rate of hydrolyss. The molar absorptvty of colored complex s 4000 M -1 cm-1 and one unt of arylesterase actvty s equal to 1 mmol of phenyl acetate hydrolyzed per lter per mnute at 37oC.

Zinc Assay Kit
Zinc is the second most abundant trace element in the body, found in more than 300 metalloenzymes. Carbonic anhydrase, alkaline phosphatase, DNA and RNA polymerases could be listed as important examples. Due to its multiple biochemical functions, zinc deficiency manifests by variety of conditions. Growth failure and stunning, alterations in immune function, diarrhea, skin lesions and alopecia are observed in cases of clinical deficiency. Subclinical deficiency has effects on immune function, synthesis and action of hormones, and neurological function.

Zinc found in the samples change the red-orange color of 5-Br-PAPS to light pink under alkaline conditions. The change of absorbance at 548 nm is proportional to total zinc level in the sample. The assay can be calibrated with zinc sulfate dissolved in deionized water.

Total Oxidant Status Assay Kit
Reactive oxygen and nitrogen species are produced in metabolic and physiological processes, and harmful oxidative reactions may occur in organisms that remove them via enzymatic and non-enzymatic antioxidative mechanisms. Under certain conditions, the increase in oxidants and decrease in antioxidants cannot be prevented, and the oxidative or in over 100 disorders, develops. Serum (or plasma) concentrations of different oxidant species can be measured in laboratories separately, but the measurements are time-consuming, labor-intensive and costly and require complicated techniques. Since the measurement of different oxidant molecules separately is not practical and their oxidant effects are additive, the total oxidant status (TOS) of a sample is measured and this is named total peroxide (TP) , serum oxidation activity (SOA) , reactive oxygen metabolites (ROM) or some other synonyms.

In the test, oxidants present in the sample oxidize the ferrous ion– chelator complex to ferric ion. The oxidation reaction is prolonged by enhancer molecules, which are abundantly present in the reaction medium. The ferric ion makes a colored complex with chromogen in an acidic medium. The color intensity, which can be measured spectrophotometrically, is related to the total amount of oxidant molecules present in the sample. The assay is calibrated with hydrogen peroxide and the results are expressed in terms of micromolar hydrogen peroxide equivalent per liter (μmol H2O2 Equiv./L) .
