This method is able to detect as low as 25 μg/ml and up to 2000 μg/ml of protein in a 65 ul sample, using standard protocol. This method may be preferred for samples containing detergents or other reducing agents. This method has a fast detection speed and low protein-to-protein variability in comparison to the BCA or Coomassie (Bradford) Assays.Melzer's reactions are typically almost immediate, though in some cases the reaction may take up to 20 minutes to develop. The function of the chemicals that make up Melzer's reagent are several. The chloral hydrate is a clearing agent, bleaching and improving the transparency of various dark-colored microscopic materials. Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine. Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75-1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
