Uric acid in serum is the end product of purine metabolism, and is cleared through the kidney by glomerular filtration. However, human often lacks the necessary enzyme called urate oxidase (Uricase), and therefore abnormal uric acid may be accumulated in blood. Recent evidences show the close association between serum urate level and cardiovascular morbidity and mortality, especially among persons at high cardiovascular risk, including those with hypertension, diabetes and congestion heart failure. The Uric Acid Assay Kit provides a convenient means for detecting uric acid in biological samples such as serum and urine. Pretreatment of samples are not required. Uric acid level can be measured using fluorometric (at Ex/Em = 535/587nm) or colorimetric (at lambda = 570nm) methods.Kit Components:Uric Acid Assay Buffer 1x25mlUric Acid Probe 1x1vialDMSO (Anhydrous) 1x0.4mlUric Acid Enzyme Mix 1x1vialUric Acid Standard (2nmol/ul) 1x1ml.Storage and Stability:Store the kit at -20°C, protect from light and moisture.
