The original file format is known as the native format. Litigators may review material from e-discovery in one of several formats: printed paper, native file, or a petrified, paper-like format, such as PDF files or TIFF images.
The biuret test is a chemical test used for detecting the presence of peptide bonds.In the presence of peptides, a copper (II) ion forms violet-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.he biuret reaction can be used to assess the concentration of proteins because peptide bonds occur with the same frequency per amino acid in the peptide. The intensity of the color, and hence the absorption at 540 nm, is directly proportional to the protein concentration, according to the Beer-Lambert law.
