Millon’s reagent

Millon’s Reagent is a specialized chemical solution widely used in laboratories for qualitative protein analysis, particularly to detect the presence of tyrosine residues in proteins. Named after the French chemist Auguste Millon, this reagent is formulated by dissolving mercury in concentrated nitric acid, creating a powerful solution that reacts with phenolic groups present in tyrosine. When applied to a sample, Millon’s Reagent produces a distinctive red coloration if tyrosine is present, making it a reliable tool for biochemical research and educational demonstrations.

Millon’s Reagent is typically used in academic, research, and industrial laboratories as a qualitative test for protein analysis. Its ability to clearly indicate the presence of tyrosine makes it a valuable reagent for researchers studying protein structure and function. This solution, available in various sizes, is ideal for both small-scale experiments and large-scale biochemical testing, ensuring consistent and precise results.
