Product Introduction
Protein content determination is one of the most commonly used and basic analytical methods in biochemical research.
Product Features
This kit can rapidly measure protein in trace amounts. It is easy to operate, fast and time-saving, can save a lot of reagents, and can measure a large number of samples at one time.
Principle
Any compound containing two carbamoyl groups (-CONH2) in the molecule can react with alkaline copper solution to form a purple complex. This reaction is called biuret reaction. There are many peptide bonds (-CONH-) in protein molecules that can react in this way. The color development degree of various proteins is basically the same. The absorbance can be detected at 520-580nm (the best detection wavelength is 540nm). The darker the purple color of the product, the higher the protein content, and vice versa. Based on this, the protein content can be calculated through colorimetric analysis.
