■ The operation is simple：single-agent operation, it can measure above 50 samples in 20 minutes.
■ Good stability： the color is stable for over 1 hour.
■ Good reproducibility：Intra-assay CV = 2.3%, Inter-assay CV = 5.34%.
■ Recovery test：X = 100%.
■ Less affected by external factors：less interference factors and good repeatability.

The determination of protein concentration is an essential technique in all aspects of protein studies and proteomics. It bases on Lambert-Beer law, namely there is a linear relationship between absorbance and concentration of the solution within a certain range of concentration and wavelength. The kit provides microscale and quick method for determining protein concentration, the operation is simple, time-saving, and can save a large amount of reagent, and a large number of samples can be measured. Any compound molecule contains two carbamoyl (-CONH2) is able to react with alkaline copper solution, forming a purple complex, this reaction is referred to biuret reaction. There are a lot of peptide bonds (CONH) in the protein molecule can occur in this reaction, A variety of protein have almost the same color degree.
