No one reagent can be considered to be the ideal or best protein assay method. Each method has its advantages and disadvantages (Table 1). The choice among available protein assays is usually based on the compatibility of the protein assay method with the samples.

The color development occurs in a two-step reaction. The absorbance of this blue color solution can be measured at 660 nm. First: Biuret reaction: CuSO 4 reacts with the protein in an alkaline medium to form a blue color complex. Sodium potassium tartrate acts as ... In chemistry, the Biuret test , also known as Piotrowski's test, is a chemical test used for detecting the presence of at least two peptide bonds in a molecule. In the presence of peptides, a copper(II) ion forms mauve-colored coordination complexes in an alkaline solution. The reaction was first observed in 1833; In Poland, the biuret test is also known as Piotrowski's test in honor of the Polis… puudli kennel
