Buffering agents / Chelating reagents / Colorimetric reagents / Metal indicators / Membrane protein solubilizers *For those considering the adoption of manufacturing raw materials and quality testing, we offer up to three products from the following product group free of charge. 【Biochemical Buffers】 1) Easily soluble in water, allowing for the preparation of concentrated buffer solutions. 2) Difficult to permeate biological membranes. 3) The acid dissociation equilibrium is less affected by concentration, temperature, and ionic composition. 4) Has a low ability to form complexes with metal ions. 5) Chemically stable, allowing for high-purity purification through recrystallization. 6) Does not absorb in the visible or ultraviolet range, making it easy to detect the target components. 【Chelators】 EDTA types are available, including free EDTA and many cation salts, allowing for selection based on application. We also offer commonly used metal-EDTA chelates. Other chelators include those frequently used besides EDTA. 【Colorimetric Reagents, Metal Indicators】 Colorimetric reagents/metal indicators are reagents prepared for the quantification of ions. These include reagents used as indicators for chelate titration using EDTA and colorimetric reagents for directly quantifying ions, including those developed by our company.
