Continuous assays are most convenient, with one assay giving the rate of reaction with no further work necessary. There are many different types of continuous assays. In spectrophotometric assays, you follow the course of the reaction by measuring a change in how much light the assay solution absorbs. If this light is in the vis…

WebPrinciple In this assay, lactate concentration is determined by an enzymatic assay, which results in a colorimetric (570 nm)/ fluorometric (λ ex = 535 nm/λe m = 587 nm) product, proportional to the lactate present. Typical levels of sensitivity for this kit are between 0.001-10 mM. Safety Information Pictograms GHS08 Signal Word Danger WebDetection principle Production of o-nitrophenol and galactose by o-nitrophenol-β-D-galactoside (ONPG) catalyzed by sodium dependent β-D-galactosidase. The amount of o-nitrophenol is directly proportional to the concentration of sodium ion in the sample. The o-nitrophenol is yellow in alkaline environment. WebSep 21, 2015 · Fluorometric assays are a little more sensitive than colorimetric assays and they are able to detect more of an analyte than colorimetric assays. They allow for a very high reading to be measured by widening the dynamic range. Some labs will combine both techniques by using a clear bottom plate. highestluxuryclub
