Biuret reagent

biuret reagent Biuret is a chemical compound with the chemical formula c 2 h 5 n 3 o 2it is also known as carbamylureait is the result of condensation of two molecules of urea and is an impurity in urea-based fertilizers.

Biuret reagent the biuret reagent is made of potassium hydroxide (koh) and copper (ii) sulfate (cuso4), together with potassium sodium tartrate. Description the biuret assay is a reliable method to determine the concentration of soluble and insoluble proteins by complexation of peptide bonds with copper(ii)ions. Measurement of total serum proteins by biuret method 107 and hofmeister8 was the first to describe its use in the quantitation of proteins and peptones but it was not until 1914 that.

Biuret test: principle, requirements, procedure and result principle: biuret test is a general test for compounds having a peptide bond biuret is a compound formed by heating urea to 180c. The biuret reagent is made of sodium hydroxide (naoh) and hydrated copper(ii) sulfate, together with potassium sodium tartrate, the latter of which is added to chelate and thus stabilize the cupric ions.

The biuret test is done to show the presence of peptide bonds, which are the basis for the formation of proteinsthese bonds will make the blue biuret reagent turn purple.

Revised fall 2010 biuret protein assay purpose and goals: to pipet accurately to prepare a standard curve to learn the use of the spectrophotometer. The principle of the biuret assay is similar to that of the lowry, however it involves a single incubation of 20 min there are very few interfering agents (ammonium salts being one such agent), and layne (1957) reported fewer deviations than with the lowry or ultraviolet absorption methods. Total protein (biuret) reagent set example: abs of unknown = 0350, abs of standard = 0400 concentration of standard = 8 g/dl then: 0350 x 8 = 700 g/dl.
