protein analysis by liquid phase colorimetry with visual assessment
Method of assessing the amount of one or more proteins, complex high molecular weight organic compounds containing carbon, hydrogen, oxygen, nitrogen, and sulfur consisting of alpha-amino acids joined by peptide linkages, in a solution using a technique in which the color of that solution, usually after a chemical or enzymatic reaction, is evaluated through the use of sight to compare the output with a standard color scale.
