Lowry Protein Assay Kit is commonly used for protein quantification. Under alkaline conditions, the proteins react with copper to form protein copper complex that reduces phosphomolybdic acid phosphotungstic acid reagent (Folin Phenol Reagent), producing a dark blue complex. It is a mixture of phosphomolybdic blue and phosphotungstic blue. The dark blue complex has an absorbance of 745-750nm.

This method sensitivity is 100 times higher than of Biuret Assay.

The UV-Visible Spectrophotometry can be used to perform 100 assays 

The Microplate method can be used to perform 1000 assays
