Uses of Spectrometers - Colorimetric Methods

Based on the earliest Biuret reaction, and improved. Protein reacts with Cu2 to produce a blue reactant. However, compared with Biuret, Lowry method is more sensitive. The disadvantages are that several different reaction reagents need to be added in sequence; the reaction takes a long time; it is easily affected by non-protein substances; proteins containing EDTA, Triton x-100, ammonia sulfate and other substances are not suitable for this method.
