WebFolin & Ciocalteu′s phenol reagent is most commonly used in the Lowry method for determining protein concentration. It has also been used for the quantification of total phenolics. In this method, protein is pretreated with copper(II) in a modified biuret reagent (alkaline copper solution stabilized with sodium potassium tartrate). Addition ... WebAn advantage of using Lowry assay test is that it is more efficient and accurate in producing results making it better than the biuret reaction. A disadvantage on the other hand is the used of Folin in its text which is not as long lasting in the experiment Ninhydrin test is a chemical test used to identify the presence of amino acids, proteins ...
