Tris(hydroxymethyl)aminomethane hydrochloride (Tris-HCl) is a commonly used buffering solution. The role of Tris-HCl in molecular biology is to control the acidity and osmolarity of a solution. Tris solution is suitable for molecular immunology, molecular biology and nucleic acid methodologies. The product has been aseptically filtered to 0.2µm and tested for freedom from DNase, RNase and proteases.
