Total Protein chemistry reagents, R: 60ml×2

A single-reagent colorimetric kit for the determination of total protein in serum or plasma using the classic biuret method. Peptide bonds react with copper under alkaline conditions to form a stable violet complex measured at 540–560 nm, delivering excellent linearity across the measuring range. The formulation is optimized for long on-board and calibration stability on standard chemistry analyzers. Liquid-stable reagent packaging supports efficient, preparation-free operation. Supplied with R (60 mL × 2).
