Date Dec. 12, 1991.A method for protein assay is a modified Lowry method in which a Step 1 reaction between a copper-containing alkaline solution and a protein solution takes place at high alkali concentration. The Step 2 reaction the products of Step 1 and Folin reagent commences at a pH of 11 and 12 in order to produce rapidly the colored species on the basis of which a maximum optical density is reached in a relatively short time and remains constant for a sufficient period to enable the required number of optical density determinations to be made.
