The biuret test, also known as Piotrowski's test, is a chemical test used for detecting the presence of peptide bonds. In the presence of peptides, a copper(II) ion forms mauve-colored coordination complexes in an alkaline solution. Several variants on the test have been developed, such as the BCA test and the Modified Lowry test. 7/30/2018В В· #pharmadigest #GPATstudy #pharmatorials Biuret Test Just in 3 Minutes In this video, we will learn about the Biuret Test: Requirements, procedure, principle and its reaction.

Biuret Wikipedia. 1/21/2020В В· The coefficient of variation of replicate analyses of protein in normal urine is 4.2%. The recovery of protein added to urine averages 103 В± 3%. Analyses of urinary protein by the biuret procedure provide close correlation with measurements by an amido black staining method., The biuret is a good general protein assay for batches of material for which yield is not a problem. The Bradford assay is faster and more sensitive. Principle. Under alkaline conditions substances containing two or more peptide bonds form a purple complex with copper salts in the reagent. Equipment. In addition to standard liquid handling.
